WORSE SERVICE EXPERIENCE EVER!!!

I’ve never received such bad service ever, I went to Haval Randfontein on the 10th of February 2025 my car was shaking a bit when I stop at the robots, they then took it for testing and told me there’s a problem with injectors, they cleaned them and charged me R1500 which I paid, when I got the car back after a week it was even worse than when I took it there, so I called them and they said I should bring it back. They told me they will strip and quote me and if I do not agree I will have to pay R4500 and take my car two weeks passed so I called for update and they tell me they are not done so yesterday I went there personally to tell them to put the car back together as it was and now they are telling me that they can’t do that the quote amounts to a R112000.00 and they cannot put the car back together cause some things were broken in the process of stripping. I just want them to give me my car back in the same manner that I took it there.
