Complaint Review: Pepboys Warminster Branch

I got my car tuned-up at the Warminster  branch in PA on 8/11/2011. On 11/19/2011, my car just stalled and had to get it towed to the closest repair shop which was Monro. When people at Monroe started looking at the car they saw that Shoddy work was done  which caused the car to overheat and blew up the 3 catalytic converters. They also discovered that few of the maintenance items that I was  charged for was not done like the brake fluid change. In fact I was also charged for a cabin air filter which does not even go in my car. I  filed a complaint with Pepboys customer service and received calls from  Brian (service Manager @ Warminister) and Harman (Area Manager). They  just played a blame game and said that Monro was trying to frame them. I have pictures of the condition the car was in before it was fixed at  Monro, but the Area manager was not interested in helping me. I had to  spend $3700 to get the car repaired.
