Shocking service and not able to fix the problem

Car has been in now for the 3rd time because the radio was not installed properly and there was a bad rattle coming from it. They replaced the radio but in the process scratched the entire face of the radio. This was not acceptable and they changed it again but managed to scratch it even more and the dash around the radio. So it was brought in again and the radio was replaced but still came back with scratches. A rattle was also brought to their attention by the alarm sensor and they completely ignored it and did nothing about it. Now I must bring my brand new car in again for the entire dash to be replaced because of the scratches. Now it is no longer a new car as I have replacement parts already being put in. The overall service from everyone at the east rand mall branch is shocking and I would not advise anyone to go there as the don't seem to care. The service is great until you sign the contract and they have your money after that they could not care if you are happy or not.
