After Paying them R100k+ They wont return my deposit.

R8 500* 12 = R102 000K After being a good tenant helped this business City & Suburb Realty earn R102 000k never paid late not one month. They would even bill electricity that felt too elevated. Yet I moved out after honoring my contract, they refused to pay back my deposit. I was sent a very exaggerated bill, even for keys they had recieved. The keys alone were being charged at R900, just to make sure they keep my entire R14 000 deposit. I am so disappointed. I use to walk around the streets of Joburg making sure I wont get ******. But it seems the real ******* are companies like this who are doing dishonest evaluations. They even want to charge me for general maintenance of pipes which is their responsibility. I am disappointed that they will even right "Thank you for your business" in the bill.You already took 100k why come after the deposit of people who gave you business.
