Complaints on bad service and attitude

I have recently been pushed out of a complex in 102 Serengeti Sands Sunninghill due to non agreement on a property sale. After removing all my belongings from the property, the agent over charged me with repairs (painting) which needed to be done in the bathroom R4142 which is hardly a surface of 2m². Without checking the actual rates, the agent mentioned that was the cheapest quote they received not providing information on the other quotation. I have been outside the South Africa on a work assignment and actually managed to arranged for couple of belongings to be removed by the commutated date. Now the same agent is threatening me to towe my vehicle away and she blocked me on whatsApp while it is the only way of us communicating. All of this because I have asked her restitute my rental deposit. She is trying so hard not to reimburse me a cent claiming that I absconded on my rental July 2021 and only mentioned it in march 2022. How do I solve this issue??
