Disgusting service

Disgusting service from the stuff. Shows that the stuff is not trained properly if they need to be told by another person what they need to do. Here's the story, went in to get a wheel alignment and tyre balancing as the car was vibrating when I would reach 90+ km/h, after they did the balancing and alignment, the issue didn't go away, went back to them to check once again, they said balancing was done fine but the problem is that the car was missing *****ets hence the vibration, was asked to go to hi-q for those. Got the *****ets done but the vibration didn't go away, now I thought maybe the issue is not with the wheel balancing, rather the suspension, took the car for suspension checks, and the guys assured me that the suspension is fine but the problem is with my one wheel that requires a lot of weights (they said the issue might be a buckled mag). Took this diagnosis from the suspension guys back to tyre mart as they have a service to fix mags, after I told them that, now they also told me the same thing and was told that I need to pay R950 for the mag to be fixed, fine. Mag goes for fixing, I use my spare wheel, the vibration goes away, I can now reach speeds of 120km/h without having any kind of vibrations. I go back on Friday to fit the mag that was supposedly fixed, and guess what, vibrations are back and there is no difference from before and after the mag is fixed. Such an appalling service I experienced, having to do this back and forth for 0 results. Funny how I took the car to them 2 times and they still didn't see an issue
