The Car Guys Circular Drive Branch in Port Elizabeth Complaint

Good day, I sign a contract with The Car Guys at Circular Drive in Port Elizabeth. This contract was to buy Hyundai Getz in Aug 2022. when I received the car there was a problem with car heater and window control panel which was not working. The gentlemen who helped me was Riano and on the same day that I received the car I address the issue of car heater and window panel which was not working. He advised me that he is going to book a car for these issues to be fix. I took the car to him and it was with them for 2days and the call me to pick up the car as he advised me it was fixed. When we tested the car there was some heat when I switch on the heater. But on the next morning when I realized that car heater is just a bit warm but it do not get hot. I then advised him that the heater does not get hot and he told me that he will book the car in. I also reported that the window control panel is still not working on the same day I reported the heater issue. He also advised that he will book the car in for both issues. I never came back to me for these issues. I called him to find out when do he booked the car and he advised me that the ordered the window panel and once it arrived he will advised me and book in the car. I waited for quiet a long time and I keep calling him several time to inquire when will he get the window part and he keep telling me that he is still waiting for supplier for the part. I even went to their office to put some pressure as this was bothering me. Every time I went to their office he keep telling the same excuse. About a month or two ago I went to the owner of this branch Shaun and he also ensured me that he will sort these issues and up until this day these issues are no resolved yet. I am so disappointed with their service as these issues were on the day I received this car and they are still my burden to me. This is unacceptable and unfair treatment to me as your client. Before I sign the contract with them Riano gave me such a great service and called me day in and day out to come and choose the car. But after I signed the contract the treatment changed and was so disgusting. Can you please attend to this and resolve my complaint as soon as possible. I am very unhappy and so disappointed with all this matter.
