Useless service providers and ********

I went to replace brake pads in December 2022which they did,and was assisted by Nolan,the next day my car was making funny sounds while driving took the car back the 1st time and they had a look and apparently didn't find anything unusual apart from the fact that they didn't fit the tyres properly. The sound kept getting worse took it back again this is all in a space of 5days and now I was told the tryes at the front are v shaped and need to be changed all of a sudden, but before I took the car to them it was fine with the same tryes. Anyways I went to Merc and the picked up the issue was the wrong brake pads installed and that the disc's needed to be replaced and nit skimmed,so I then replaced the New brake pads from Supa Quick Kyalami with the correct pads. A bunch of unprofessionals who clearly don't know what they are doing for the same issue and
