that's what they said to me, should I go in and demand to know the full reasons why and ask for it written down?

Hi i was told to come here by a relative for some advice, im sorry my first post is requesting help. Ive recently recieved an eviction notice from the court. on the house ive lived in for the past 4 years, it states we are being evicted due to a breach of my tenancy agreement. i phoned my letting agent up and asked him why i was being evicted. to which they replied i breached it by decorating the front room, and there was some steel drainpipes on my drive (6) as i did not have the means to take them away at the time as they were left by a friend. Also another thing they have stated is there is damage to the front door. The front door is a UVPC door which has never closed properley since we moved in as it catches on the top part of the lock so you sort of have to slam it. however one of the times we had to slam it shut in the bad weather we had a few months ago one of the 2 panes(which are sandwiched) on the door smashed. it was the pane of glass that blocked people looking in so the only pane now is a clear one that looks right into the house. As for the decorating, i only decorated the front room due to the wall paper peeling and the fact i have 3 children and lived here 4 years so obviously its going to get damaged and scuffed. However every person who has visited my property has complimented how well done the decorating is and better than what was originally there. i believe the reason they are being like is is due to the fact most the houses on my culd-i-sac are rented and recently the value of the rentals has gone up however ours stayed the same, and i feel i'm being made a scape goat just so the owner and the agents can earn more cash. since living here ive paid for the boiler to be repaired twice myself, as every time i report a repair it gets ignored and i'm not having my kids going cold. i told them the conservatory leaks and i had to turn the power off in there as it trips the electrics. the front door isn't working properly(they ignored and then glass broke), the cooker which is built into the units doesn't work properly. the kitchen cupboards falling apart, split bath panel and also bath leaking into dining room , you can actually see the outline of my bath on the dining room ceiling. funny thing is in the garage since we moved in, has had a area boarded off with a padlocked door which only the owner of the house has access to, which contains tools and diy stuff, however all that stuff so close and they still dont do repairs. even tho i pay rent for the whole house and i act as a storage locker for the owners stuff. i dont now what to do. how long by law do i have to get out, and if that time passes and i havent got anywhere do i get an extension as i don't want to be on the streets with the kids. thank you for listening to my rant
