Not acceptable behaviour

Hi, anyone can help with not acceptable behavior of landlord (shared house) ? Before moving in we were promised about finished repairs and house ready to move in and which wasn’t. He is entering room with no notice when I’m at work (made my bed just to take picture) told me to move furniture back to places). Deposit wasn’t protected, not doing repairs in my room after all ceiling fell down (2weeks) had to clean room my self wet mattress horrible smell, couldn’t sleep in my room for two weeks and still was asked to pay rent. Not finished repairs in 5 weeks and rubbish in garden not beeing cleaned. Citizen advise didn’t help, council didn’t help, solicitors wants huge money. Whi can help me to finish contract and get my money back? Can I report this landlors as I found room in open rent?
