Advice please...Repair charge when guaranteed for 2 years

[Needhelpwithcurryspcworld]

I posted this on my page and someone recommended this group for advice, thanks 8n advance for reading.... 
This is a desperate attempt for any help or advice as how to proceed please.... so those who know us well will know that my son has additional needs and when I need some down time, or when he's becoming dysregulated I use the switch lite his grandparents gave him, he's obsessed with technology and games and he kinda zones out and calms... so when the left joystick control started "drifting" (I've since learnt this is a well known issue with nintendo )  he began having meltdowns as it was not doing what it should.... his character was walking backwards and wouldn't stand still etc.... so I entered onto a web chat with currys and a lovely colleague Bindhu explained as it was purchased Dec 2020, and therefore not 12 months old, the fact it was a gift and I lived in cornwall and my parents up country i didn't have box or receipt was no issue, as conversation progressed Bindhu said due to the significant inconvenience on our lives we could simply return to our Cornwall store and give details, and it would be resolved instantly, replaced... which was such a relief as I was worried about Jack having to wait for repairs etc... upon arrival to the store the desk colleague says no replacement I didn't purchase it my mum did, but they would send it for repair... 28 days... he didn't care about Jack or myself and the impact that would have.
I sucked it up, as a single mum at least Jack would get his switch lite back, I just had to somehow manage 4 weeks! 
Roll on until last Tuesday I had a voicemail from currys telling me my switch was not under warranty and required me to call nintendo quote a repair number and pay 53 quid within 14 days or the console would be returned unrepaired. I can't find any contact number for the store so return to the webchat ... where a Sara very politely apologises and seems to understand my confusion and frustration... she promises me the store manager will call me back and resolve the issue it will be fine. The store manager calls me back and very defensively opens the conversation with her staff have been trying to call me all afternoon! I do apologise currys but I was recovering from a hospital procedure I had myself that morning!!! Not that all this stress and inconvenience is helping me at all like! Anyway after a conversation she basically stands by the fact that they are simply the middle man in the scenario and if I do not call nintendo I won't be getting console back repaired. After my 16 yrs retail experience I explained as customer service lead if someone provided proof of purchase and it was not fit for purpose within 12 months it would be replaced no questions asked. She says oh yes we can do that with kettles etc but we won't do it on consoles! As far as I  concerned the product is gaurenteed for 2 years on the sales contract my mum entered into with Currys... like a two way exchange so how they are only the middle man and can't do anything is beyond me.... in my retail experience the electrical returns were all sorted out behind the scenes not the customers issue. We purchased from currys with a 2 year gaurentee and within 8 months it's faulty! And now I have to ring nintendo and I have to pay money. Anyway after being really dissatisfied with store managers response and attitude towards me I waited until 9am the next day to call nintendo - the first guy cuts me off, the second guy says it needs paying for ... on inspection it didn't switch on and they found damage to charging port, not under warranty... they also found the left joystick issue which I sent it for repair because of, which IS under warranty, and on top of that the mother board and the right joystick were also found to be defective and also covered under the warranty! 
I sent it off for 1 issue to be told there is 4. 3 were unknown to me, and we certainly didn't have issue switching it on or charging, the nintendo man said not now maybe but in the future you would have issue with charging console and they cannot send it back knowing its not 100% OK.... this point I understand however it not my place to find and pay 53 pound for an issue I wasn't having because its not 100% and will become an issue eventually considering they have admitted to 3 other faults being under warranty. . . 
The stress and pressure when my son is expecting it back soon, and I am undergoing tests- I just needed it sorting... I returned to only way I could contact anyone and had a Web chat with Yashika.... I explained the entire saga, and even felt I should make her aware of my ecg tests so I didn't miss another call because of my health! I explained my consumer rights as I see them, that a product should be of satisfactory quality which it's not, even if you blame my son for the charging port which wasnt a problem for us... the product clearly has faults which are not due to  him! Its not 8 months old and guaranteed by currys for 2 years- no durability! It's not free from minor defects as stated above, and can't be fit for purpose if he can't play his games and it's a games console!
Let alone the fact the first person said it would be replaced no issue due to the significant inconvenience, and then the opposite being said in store. The 2nd Web person again promising it would resolved and manager would call. Then the poor attitude and manner of the store manager when I was recovering from a hosp procedure. And then after an unsuccessful conversation with nintendo and a fourth Web chat with a currys employee again this time I was assured it would be escalated and "surely replaced or refunded... and the resolutions team would reach out with in 24 to 72 hours" they were disconnected whilst I waiting for the complaint reference number to be generated.... shalender then appeared on the chat, they told me they couldn't help me at all with the issue. When I refuted and explained I been chatting for couple of hours dealing with the issue,and simply needed the reference number of complaint. They said they were denying help....
Then when challenged they said they could read all the chat I had previously and then proceeded to ask me all the questions yet again! After this I was supplied with a complaint reference number. So fast forward a week... accounting for bank holiday weekend the 72hrs for the team to contact me lapsed wednesday! I have heard nothing! 
Yesterday I have again returned to the webchat where Abhijeet has told me I can't be helped as won't pass security checks? Then told even if he found complaint he wouldn't deal with it... then said they were no complaints department then gave me reluctantly an address to complain to... when I asked about details of the ombudsman for currys I was told they don't have access to details to pass on to me... or a contact number. Then said the complaints team will call me... I explained they were meant to call by wednesday and hadn't so can I have the name of complaints manager and number and was told no there is not one. ... 
The problem I have is nintendo are currently holding the console until 7th September at which point they are sending it back to store unrepaired unless the money is paid. By the time i post a letter and it gets read were going past the time and the distress and inconvenience for myself and my child is already ridiculously massive! 
I don't feel comfortable going into the truro store after how the manager was on the phone with me,and also embaressed that I even have to discuss my health with anyone it should not be relevant. 
I just want my son to have his switch replaced for one that is fit for purpose and to not have his grandparents swizzed still paying for a console which currently we don't even have and they want 53 pounds from me to fix.... 
Help! I never in my life have experienced such incompetence and won't ever use them again for anything, but that does not help me now.... so just wondering if anyone out there has had issues with currys before and how they resolved it.... and also feel its my public duty to warn people to stay away, because the stress and hassle is not worth it.

Drift is not common on just Nintendo. this house is a nintendo/xbox house and we all get drift on the controllers. 

I can fix my own drift of the switch original console but the problem you have with a lite is it needs taking apart. This can show other issues with the console What have they said the other 2 problems are, l know both thumb sticks are drifting.

I'm terribly sorry but with the best will in the world, you have posted an extremely large solid block of text which is difficult enough to read on a large screen and impossible for people who are using small screen such as a telephone.

Also you have posted the same large block of text twice in different places.

I have merged them and also locked the thread and I would be grateful if you could repost your story but this time in a bullet pointed chronology simply dealing with the facts of your problem so that we can get to the root of the problem quickly and give you the advice you need.

I expect that we can help you but we need the story to be accessible not only to us but others who will be interested to see what your problem is and also what solutions we can provide.

Please repost your story on a new thread. Well spaced and punctuated and without the narrative.

Thank you
