NO CAR FINANCE BOKSBURG IS THE BIGGEST ****

I have been renting a car since April 2018. (rent to buy) for 5 years. 2022 October just 6 months before owning the car they came and repossessed the car after missing 1 month payment and had made arrangements with them. I fully paid the amount in arrears in January of 2023 and went to their offices where they promised to give back the car in 2 days after they have checked if there were any repairs. made. 2 days later the car wasn't back and i followed up with them. In my shock they told me that I have breached a contract and I am not getting a car back. Now the biggest issue is that they are still debiting my account and I am not sure why because they refused to bring back the car.
