"Unprofessional letting..."

I moved into a flat on beresford road saturday 20th may. And within 24 hours the bedroom window broke when I opened it. You could not close it. It needed replacing. I had to slam the bedroom and living room doors to close them. I could not even have a shower because it was scolding hot. I was lying in bed listening to the vibration coming through my bedroom ceiling from whatever is going on upstairs. The place had scaffolding around the building. I left my property in great yarmouth because the landlord wasn't interested in carrying out the repairs from the constant pipes banging and vibration of the boiler coming through my bedroom ceiling from the flat above me. And I again have no peace after moving into this property. The seals on two of the living room had broken down. So they got replaced. Then the bedroom seals broke down and that will soon be replaced. And now another living room window seal has broken down. Three of the living room windows have privacy film covering them. And in my opinion this was put up to try and hide the condensation inside them after the seals has broken down. All the windows in the property need replacing. There is quite a big gap in the bedroom door now since it was planed down yesterday. The living room door is still yet to be repaired. I emailed this agency today to ask to personally speak with the landlord, but I was refused. And I've been told that the landlord will not be replacing the windows. I paid the deposit and 6 month's rent in advance to move in. Almost £4000. I have uploaded 3 photos. One of the other living room windows with the privacy film is trying to hide the condensation inside because the seals have broken down. One showing the seals split on the other living room window. And two of the bedroom door where you can clearly see the gaps at the top and bottom.
