Unsatisfied customer service

I bought a Hyundai Grand I10 about 3 months ago from them, it has been financed at Absa Bank. When we visit the dealership to look at the car there was quite a number of problems and was promised that all will be fixed before delivery. After a week the car was delivered with NO fixtures done at all! After complaining and battling they took the car back and after 2 weeks the car was delivered with "some" fixes done. We were promised a left mirror to cover that was ordered but never received. The wheels were in a state and wheel caps was damaged therefor wheels only last a few hours then it needs air again. They cover it up with wheel caps and fastened it with cable ties, we could understand why we battle still with the wheels for these past few months and took off the wheel caps, only to find out the wheels was just covered up. I told them there is a noise in the engine but hasn't been fixed at all, we took it in and was told that it was a pully that made that noise. I asked again for assistance yesterday but nothing.... VERY disappointed client!
