"I was promised the property I ..."

I was promised the property I was moving in to would be cleaned, IT WASENT. every time I spoke to them they just fobbed me off. The girls that work there talk down to you. I was told to decorate, the day the I finished I was told I needed a guarantor all over again to renew my contract. Once I called them and gave £500 and I explained that I was sorry but the other £295 would be 9days late because my job had stopped, keeley (manager) was fine on the phone but as soon as she got off she emailed my guarantor saying if it's not paid by her they would take her to court. Ha ha none of what they is right. After they served my section21 they were still sending me letters asking me when I'll be in the office to renew the contract. Time and time again they got things WRONG!!. Rubbish customer service. Everytime I asked them who to complain to, I was told keeley was the director of the whole franchise. Lies lies lies I could go on and on... Iv still not had my deposit back.
