lost deposit

We started to rent a flat from key rentals last year. From the get go we realised that they have no interest in performing any services that would be expected from an estate agency, as we where given a form to fill in any issues in the flat that needed to get looked at before moving in. After submitting it with photos as proof nothing happened, not even a reply. So we left it, paid our rent as per norm. When we moved out early we where informed of penalty payments, so we paid and like usual we sent a conversation email for the payments. On the day of inspection everything checked out. I was informed that the deposit would be paid back with in 14 working days. The inspection was done on the 29th of Jan 2015. We have been contacting key rentals with absolutely no reply and only empty promises and bull statements that the payment is in this process or handed to this person to pay. Yesterday was:\it would be in your account today". In short Key Rentals took our money with a super smile and gave us no service. On top of that we are a deposit short as I don't see this issue being resolved in the future. Don't make the same mistake!!!"""
