Irritating and poor customer service at Renew-it Randburg

I have an issue with my car which was badly fixed by Renew-it Randburg. I met with Miway's assessor, Wendel at Renew-it Randburg and it was agreed that indeed there is extremely poor workmanship and Wendel will get in touch with me to inform me as to when the car can be taken back to renew-it. Wendel confirmed that Renew-it did not replace the damaged parts with newparts (as per what was approved), instead they badly fixed the parts and returned them. What is further disturbing is that l am now receiving these messages from both Renew-it and MiWay that proclaim that my car has been fixed. This is very unprofessional and irritating because l haven't been told to take the car back, yet according to them the car has been fixed again. I am very disappointed by both Renew-it and MiWay's unprofessional conduct. They are taking their customers for a ride.
