OK, I'm just worried that if I ignore this it goes back to hmrc and I owe the original amount again and can't fight it due to my lack of evidence.

Can you elaborate? If these guys are offering me to pay half the debt to clear it completely and get the hmrc off my back why do you advise against this. What are the alternatives? Thanks for your help

Quick update, Sar was sent off but heard nothing back until today when I received a letter from past due credit asking for half of the money to clear the debt. Should I deal with these people? I don't believe I owe anything but paying half to get rid of them is tempting! If I continue to deal with hmrc they still may want full amount or may refuse to deal with me at all?

I arrived home yesterday to find an unexpected letter from HMRC requesting I pay them over £500 for an over payment from April 2009. My issue is that I wasnt aware that this over payment occurred as it would have been paid into my ex-gfs account I have no idea how to proceed I have no evidence which explains why there was an overpayment or even if what they are telling me is correct. I split up with my gf in early 2010, I have since moved house multiple times, have changed bank accounts etc and do not have (or have ever had) any documents relating to this. I gave them a call and they told me it was for a debt in April 2009 and that my ex had paid the other half (so she must have admitted that it was a mistake??). the adviser i spoke to on the phone accused me of lying and said there was no way I wouldn't know about this and they they have sent me letters in the past which is simply not true. I have said I will dispute the claim but I have no evidence to the contrary and I am unsure what I can do, it looks as if I may have to pay this? please help!

I recently sent my phone to back to HTC for a repair under warranty as for the last 3 months I have had issues which were as if i was repeatedly and rapidly pressing all of the buttons at once, the screen was going crazy and i was unable to make a phone call or send a text message. The day after the phone was collected I received an emailed quote from HTC demanding nearly £150 to repair the phone. Naturally I called them to find out why I would have to pay this charge and understand why it wasnt covered by the warranty. I was told that the phone had a known hardware fault known to them as the "helicopter screen bug" and that the motherboard would need to be replaced; however, as I had installed a modified version of their software on the phone the warranty was voided. I find it hard to believe that they can refuse to fix my phone which has a well known hardware defect because of the fact that I installed my own software. I argued my case with a member of the customer services team over the phone, who appeared to agree with me but he still said nothing could be done, I stood my ground before he told me he would arrange for a supervisor to give me a call the next morning. I never received the call back and now want to call them back myself to see if i can resolve this. Am I correct in what i am saying, should i be entitled to have the phone repaired for free? if they continue to refuse how should i proceed with this? Many thanks for reading!
