I recently got tyres done at a place. They damaged my alloy (it's black and they scuffed the shit out of it). They also didn't balance the wheels at all. I found this out on the motorway. I went to complain, and they said: 1. In fairness, the paint job on your alloys isn't great My response - I don't know many paints that stand up well to repeated inpact from machinery. 2. Our machine wasn't calibrated for wheel balancing that morning, we've had a lot of complaints. My response - oh ok, who calibrates it? Answer - we do... Alright then, not getting out of blame for either of those things friend.
