Non Compliance wrt paying back deposit

I was leasing out at one of the elegant line flats in Potchefstroom. I moved out on the 31st of October..After signing the documents I was informed my deposit will be in by the 15th..On the 13th I received an E-mail from Mathapelo Mataboge stating that she has attached a lease agreement.. she would appreciate that if I could sign it and send it back.. but the subject says non-renewal.. I am confused as to how am I requested to sign a lease agreement instead of a cancellation. I tried calling the office wanting to understand the issue..I was informed that Mathapelo went out, I called at 14:00 same day I was then informed that she did not come to work. On the 14 of November I sent an E-mail trying to reach out to the member however I did not get a reply from Her. I Then called the office again on Friday the 15th of Nov, I was informed that Mathapelo is not in the office she will be back on Monday. I then called since mother till today they are not taking my calls. I need an urgent response on this matter and my money deposited back!
