Unfair treatment by Properlet Bloemfontein when I rented on of their flats

I am writing about unfair treatment I received I experience from the property agency for the Flat I was renting Willow Glen 407. This happened after my locks were changed without my concern and a threat to remove my belongings from the flat on January 2nd 2019. I initially sent a notice of non-renewal (22 November 2018) of the existing contract as I was going to move out. The contract that I signed states that two months period notice is required prior to moving of which my notice was going to serve from 1st December 2018 until 31st January 2019 (as per agent response) as I am liable for rental payment until the day I move out and I had no problem paying because that is what I have signed for and I understood the contract signed. I have emails between myself and the property agents. I emailed the agent that I will be moving out on the 22nd of January 2019. Since than the locks of the flat I rented were changed without communication of my whereabouts, I was at work on the day. The other tenants staying opposite my flat were shocked as the guy wanted to remove my belongings and left a note that if I want access to the flat I should call me. Again no one called me at that time, the security guards on duty that day were also shocked as they knew that I was still staying there and I had left for work. When I got back and I called the number that had been left on my door, the guys came and told me that he has been advertising the flat as I am not stay there. I asked how that is possible as I have been paying rent and have never missed any payment and I kept sending my proof of payments. His response was that I am not on their system, he came to change locks as there are new tenants waiting to move in. the next day on the on the 3rd of January the tenant that witnessed everything came to my flat to check if I managed to gain access and told me what had happened and what the guys were about to do which is remove my belongings out of the flat. No one called me from the office to explain their mistake. I went to the office to demand answerers, and the lady at reception told me that I gave notice so she removed me off the system, forgetting that on the email that I received from them (agency) my notice serves for two months and I gave them the date that I will be moving out. I moved out on the 4th of January 2019 under a lot of pressure and stress which resulted in me missing work on the day. My lease was still not terminated, I did not sign anything to proof that I have terminated my lease. This is causing some stress because my privacy was violated as a tenant, there was no communication. Should I have not gone home to collect something that I needed urgently I would have slept outside. After I had moved out or forcefully moved out because according to the agency I gave notice on Tuesday the 8th I was called 3x times by the agency first call I was asked when a I handing in the keys? Now I was not around Bloemfontein at that time and I informed the lady that called. I told her I will bring the key upon my return. Second called I was asked when can the final inspection of the flat me done? Because new tenants have to move in. I responded that Friday the 11th I am available and the time was set for 9:00 am. Third call I received I was informed that the final inspection is canceled and that the agency will do the final inspection without me being present. My question is why should I be liable to pay rent when I did not stay until the 31st of January? The final inspection done without me I have no knowledge of what the agency might say what is damaged in the flat. I know that the only thing damaged when I moved in was the window rail on the one side of the window, I was promised that it will be replaced and it was never replaced. I left the place clean as I hired a cleaner to clean. I would appreciate it if the agency can pay back my deposit of R3000 and not be liable for the January rental payment as I have moved out before time and not as per the contract agreement. For example things that the agency did which is violation: • Have appropriate final inspection carried out with me being present. • Give me a signed document of terminated lease agreement • Abide by my right to privacy by entering my flat without my knowledge.
