Bad service

This company is a ****. They falsely advertised an apartment at Ormonde View Estates. On the adverti*****t it was said the lease will be 12 months, the rent R7000 and that the place will be available on the 6th of September. After I paid for everything ( the deposit and rent), they are now telling me that the landlord wants to change the lease to 6 months and increase the rent 500, the landlord still has his things in the apartment I don’t even think that he’s ready to move out. I told the agent that I’m pulling out since the landlord is unreliable and going back on his word. The agent promised that I will get my money back but it’s the 25th and they still haven’t repaid me. When I call, they are no longer taking my calls and I need my money back so that I can secure another place. They wasted enough of my time, I want my money back please!!!
