What are my rights if facing retaliatory eviction and harassment?

I am facing retaliatory eviction after reporting structural issues in my rented flat. The landlord has been harassing me with unsolicited workplace contact and offensive messages. I have documented high electricity bills due to a faulty AC and contaminated water supply. I am seeking compensation, a proper inspection, and a refund of my deposit. I am awaiting a response from the landlord’s lawyer. I need legal guidance on my rights and the next steps to protect myself and resolve the situation.
