Weinprop doesn’t want to pay me back my deposit

So I rented a unit at library gardens apartment in Helen Joseph street. So my lease I was ending month end of November and I informed them on the 4th of November that I won’t be renewing my lease. I was then informed that I have informed them late and that I have to pay rent for December. Mind you I did pay rent and still moved out. So I’m here waiting for them to then send me my deposit month of December, cause on their contract it does state that deposit will be payed the next month end. Cool, I wait still month of December I get no notification of my deposit, I then contact Peter who is the building care taker to ask when is my money going to be transferred to my account. He then tell me the stuff only return to work on the 8th Jan to the office. I contacted them and I get to speak to Maureen who is trying to explain that I asked to not renew my lease late and and, I’m late ok I get that y’all told me I should pay rent because of that and I did but why haven’t I gotten deposit. She didn’t even know I payed rent, went to check her emails and she sees I have payed rent. What shocks me is they she wasn’t aware I payed rent for unit 309 for December like really. She then tell me oh no sorry I see yes you actually paid rend I will then process your request for your deposit. I then ask when can I expect this to be done she says latest will be the 19th of January shocked but I’m like ok I’ll give them time cause the latest is Friday so meaning it can be processed anytime during the week if not lates with that Friday then. Well today I send email she ignores my emails I haven’t heard from her with regards to my deposit being paid back to me. Maureen from Weinprop is now ignoring my messages with regards to my deposit been paid back to me. I need help
