Unhappy tenants

I am not happy on how I have been treated by this agency. 1st.they let me move in to house full of mould I have pictures of the bathroom they complained about. And trees ever growing in the streets we had to cut. They complained a stove tray, and we never even used their stove cause we have a gas stove with no oven. Than they used our deposit money to fix stuff that was broken "apparently" yet nothing was fixed when we moved in. Instead we had endless struggle to buy electricity cause their meter was blocked. We had to overnight without electricity and it was only sorted out the next morning. The yard weren't cleaned when we moved in. They only cut the grass. They left us with **** and mould on the paving as well as the boundary walls. We cleaned the space to live in. I have photos to proof cause I took pictures. We had to live for the whole year with a leaking sink. We had to keep a bucket underneath the piping and emptied after each use. Our water bill was sky high. It was not fixed even after I reported it. We moved out on the 1st march and up untill today we have not received our deposit money back. Where can I have this reported. Everytime we fix something again they call out something else to be fixed.or cleaned. There was nothing broken when we left. Still, no deposit back. We left the pool with sparkle in it. It was blue when we left. Filled it with water and now the pool is green cause they don't brush it. The pool is green after a week. Am I suppose to clean the pool again? After I left it clear . Please assist me on where I can report this. I'm disappointed, feel humiliated and furious about how I been treated by them.
