Deposit and bad service

Good day I'm not a person that likes to complain but i have not once in my life had bad service like i got from just property's. I moved in by a unit 1st of January i stayed in the apartment for 5 months but because of poor service me and my husband decided to break lease and move. There where a number of faults that needed to be repaired which the agent had noted. Ive send photos of the faults to agent had discussions on the phone and some of them was spoken about in person. On my email regarding the repairs the agent did not reply after contacting him no body was send to fix the repairs. The following faults was listed there was 2 faulty doors, a drain pipe was not correct which made the place smell really bad, small water leak, oven door was faulty, roof was leaking and badly damaged. When i contacted the agency 2 give notice they said that im going to have to pay break of lease fee which i was fine with the amount of R1500 the lady i spoke to said that im going to also pay the remaining commission. I asked her how much that is so she worked it out and told me about 1300 as i believe the agent did not do his work i agreed to pay only half of the amount. Now they want to only give R1900 back of my deposit which was R6250 i feel this is not the correct amount which means the agent gets about 8000 commission which makes no sence. The commision amount went up from 1300 to an amount of 4000+. These people not contacting me at all its now been 1 week since ive spoken to them saying that i want the amount of 4100 in my account as that is the deposit- 1500- 650. Its been 2 weeks since i gave the keys to them still no deposit. I complained about bad service regarding repairs and agent not contacting me or doing his job now my point is showen again they still not giving me good service now please can i just have my deposit so i can get these people out of my life horrible servoce truly will not use them again
