Horrific service from Naseem from InspectaCar Centurion

I bought a vehicle from InspectaCar Centurion on the 21st of October. I took the car to balance the tyres and do the wheel alignment on the 28th of October and also had the shocks tested. HIQ advised me they cannot balance the front tyres since there was separation on them meaning the middle of the tyres where worn while the outsides were still fine. They also advised that all 4 shocks needed replacement since they were below the required 0.30 on all 4 shocks. I contacted the salesman Wickus who adviced me to bring the car in order for them to verify it and resolve the issues. I took the car on the 6th of November since they had to make arrangements to take in the car. Today they called me and advised that the manager Naseem had his workshop test the shocks and according to them only the front 2 needs replacement however they are not prepared to replace it since they do not know whether I drove over a pothole damaging the shocks. As well as I had driven the car 4 weeks already. It has not been 4 weeks yet and I advised them of the issues after 1 week. He also advised he xannot replace the tyres since he can not establish how I drove the vehicle, for the first week??? Terrible service from Naseem.
