Audi East Rand is a nightmare

Due to lack of better words I guess useless will be the best word to describe the service I received from Audi East Rand, took my car because of the vibration I had and they told me that the vibration was coming the rim which I ended up fixing all four rims but the vibration was still coming

After they told me that they checked my car with a different sets of rims from one of their pre owned I was told that the problem was not the wheels but CV joints which they promised to change but the next day they told that the problem is wheels again so I must be a new set of wheels

I’m so ****ed because they are speculating and I must pay the money for their speculations
