They should never have done any of that work. My husband is a mechanic in The Colony, and the Walmart here will send the cars to an actual auto repair shop that need anything other than a straight oil change, tires, or batteries. Don't give up on your complaints. Write or call whoever you can. They should pay for any repairs due to the damage they did (the walmart in TC does, and has...my husband has done the work where walmart picked up the bill). Unfortunately, I don't know any lawyers, but don't give up!
