Contract expired 28 February - now issues.

Our contract expired end Feb, and when we moved out, they **** and said it expires end March. After proving them wrong, they tried to keep me there, after I gave them notice in mid Feb that I'm moving out and not renewing the contract. They are trying to keep my deposit, stating that faults in the home from before us is our fault, and now that it is sorted, they say that we should've given a month's notice. The contract specifically states that they are supposed to contact me 40 - 80 days prior to the date of termination, and they never did. After they finally woke up, and tried to force the new contract fees on me, and I didn't want to go ahead, now they are trying everything in their power to keep my deposit.<br> After they numerously told me that after the first issue was resolved (windows) that I'd get my deposit, they **** once again. I need the deposit for my new flat, and this is becoming an issue. DO NOT TRUST KNIGHT ESTATES EVER!!!!
