G.M.C. Garage

My car was moved from it's original parking space and moved somewhere else in the garage. There was damage to the sides of my car. I called every day to GMC and spoke to low level staff, who would handle the problem. There was no resolution done, so I contacted by email and phone and letters To [redacted] CEO and other members of the organizations. I would be able to leave my name and telephone number, but again no responses, no return calls and no letters. I decided to hold 2 months parking fees of approximately $650 to rectify the repair of my car. And I have been current with every months parking rent. Now, a boot has been placed on my car and it can not be driven.
