The Pep Boys

Pep Boys installed aftermarket parts on my car and my car can only use market parts, so the repair that they did to my car, which was all dealing with the coolant system, and thermostat, only lasted a year for six-hundred and ten dollars. Now this year I've had to have the same repairs done to the car at the dealership for another five-hundred dollars, and I'm not happy about it. I called the location and they were unwilling to work anything out with me. I have receipts for all the repairs done, and I'd like a full refund for the work that they did on my car, because it was improperly fixed and has only caused me further repairs, which I've listed above.
