Utterly disgusted customer

I am just utterly disgusted with this company and am just lost for words now. I have logged a number of complaints regarding this company and the service is just pathetic. I have a rent to own car with them which had a mechanical breakdown in the 06 of January 2025. They took the car in and said it was sorted and the car had the similar problem again after two weeks and they took it in again. Then the told me the second time that I had to cough up another amount as it was a different mechanical case. I did that and now the car has the very same heating problem now for the third time which they said it was sorted and I paid separate amounts for both of these issues. I just don't have the energy to vent my frustration regarding this company and Anwar who's is the service advisor in Sandton is in this thing as well. He was the one who told me when the car was towed for the second time the problem was a different problem and I had to pay another amount when this car was towed for the second time with the very same problem. They can just come and take their car because am gatvol with these guys. Clearly they have bush mechanics at the workshops who don't have a clue what they are doing. This car is now having the very same problem that they said they have fixed TWICE, different payments. I am just utterly disgusted to the core with this company.
