Tire mounting and balancing

All 4 of my wheels were damaged in the same way while getting tires mounted at Midas in Warrenton, VA. There are now scratches on the outer surface of each wheel. Mike, the owner, said that there was no way that they could have done the damage and offered to have it corrected by a third party at a cost of $360 to me. As other customers have experienced in other reviews, Mike was arrogant and rude - to the point of arguing with another customer on the phone while I waited to pick up my now damaged vehicle. I won't be going back for my own reasons but also because Mike told me that he would not service my vehicles in the future.
