I saw an add on gumtree for a private let and on the advert it states landlord wanted two months rent deposit all was fine I moved in then the problems started landlord didn't fix a leak and left it for two weeks now there is a hole in the ceiling, landlord got told the house needed major work so he gave me my notice to quit to do repairs he also stated in a letter that he wasn't giving me all my deposit back because my little boy squashed goo into it (I have since removed goo) so I text landlord saying I had cleaned it and I expect £1200 of my £1500 deposit back his reply that was upto him, I found out he hadn't protected my deposit into a scheme sent him a letter before action saying if we didn't come to an agreement I was taking him to court he said good luck the money I gave him was first and last months rent. I get housing Benefit that was back dated to the day my tenancy agreement started. Where do I stand If I can prove landlord took it as a deposit?
