Terrible "After Sale Service" from Weelee Centurion

I bought a Hyundai Creta from Weelee Centurion on the 07 February 2026 (Sales Executive was Kabelo Leshoro). I found an intermitted rattle at times, while driving in the days after I've bought the car. I then called the Sales Executive on the 09 February 2026 and told him about it and also raised the issue of an service request light coming on, inside the car. He said he will come back to me. He didn't revert back to me, so I emailed him again on 18 February 2026, and then I was forced to take the car for the service, which was at Hyundai Hatfield. Please note that I have just bought the car from Weelee Centurion, and was about to buy another one, if all went well. So, I went to Hyundai Hatfield and they said and even showed me on the Service Book, that the car has missed a service and was thus due for the next service (which was the service that I had to do and paid for). According to Hyandai Hatfield, seeing that Weelee did not do the previous service whilst selling this car as "Platinum" status and Dekra approved, they (Weelee) should at least assist me with the service fee. I was, and basically still is, in a predicament because I had to service the car but still couldn't pay for the rest of the repairs as needed and advised by Hyundai Hatfield. After several emails to this Sales Executive (***) and to their Customer Service department (***), I still haven't received ANY response from them, not even a phone call ! I have requested them to register the car in the other shareholder (my wife) name as they said they have a challenge to register it in my name, but once again, the car's license has now expired and we still does not hear from them. They are pathetic and I am about to name and shame them on social media, and to forward this complaint to the Ombudsman. Please assist us in whichever way possible ?
