Big O Tires

I am very upset with Big O Tires and the service my mother-in-law received ultimately resulting in a threat to her safety and costly repairs. She had taken her 2007 Dodge Caliber to the location in Clarksville, In. to have her tires she bought from that store to be rotated a few months ago. She had informed my husband she noticed the front passenger tire was showing major signs of wear so on 05/27/2013 (Memorial Day) he went to her house to put a spare tire on before she went to work. He could not loosen the tire because Big O Tires had rounded off the lugnuts. Big O Tires was closed on Memorial Day so we wanted to take it to the closest place open, Valvoline inside of Walmart. They also could not get the lugnuts off and did not have the ability to repair it that day. Ken Towery was the closets place that was open on Memorial Day so we drove it over there to see if they could repair it. They had to end up cutting off the lugnuts to even get the tire off. When they did get the tire off they ran into another problem. Some of the threads from the holes in the hub assembly were completely stripped. According to the technician at Ken Towery, the damages would have occurred when the lugnuts were over tightened. This caused very unsafe conditions and costly damages to the vehicle. Ken Towery said it would be $630.00 to replace the hub assembly. We ultimately ended up paying $100.00 for the labor already done to the vehicle at Ken Towery. We wanted to get another quote, and as we did not trust Big O Tires to take care of this issue properly because of the incompetency of their technicians, we decided to get a second opinion at Hoosier Brake and Exhaust in Jeffersonville, In. Hoosier Brake and Exhaust confirmed the problem was a result of over tightening the lugnuts and the entire hub assembly would have to be replace. For parts and labor the total bill was $550.00. Because of the mistake made by a Big O Tires technician, it caused a total financial loss of $650.00, stress, time, and a vehicle that was technically unsafe to drive after the initial damages occurred. I have been in contact with Big O Tires and have spoken to Barbara in Consumer Relations as well as the manager of the Clarksville, In store, Doug Skidmore. At this point, the only compensation they are offering is $350.00, a little over half the loss. this is not an acceptable offer. This mistake was caused by them, therefore, it should be fully covered regardless of who did the final repairs. We wanted the issue handled by someone we trusted and unfortunately Big O Tires was not at the top of that list because of the incident that occurred. We are very dissatisfied with the outcome of this situation caused by a Big O Tires technician, especially considering it caused damages that were a threat to my mother-in-law's safety. I expect full compensation for this hazardous mistake, not half.
