I was having a simple spark plug change done just before moving from yorktown, virginia to california. Pep boys called and told me they had broken off two of the plugs in the engine block and could not do anything to fix the problem they had created.
They even admitted they had not used the break-free lubricant used by most mechanics. Mad as a hornet, I had to have the car towed to a true engine mechanic (at my expense) who magically changed the other six plugs without a problem and got the broken plugs out and changed. Pep boys has a network of "service" numbers to call, each of which pass you on to the next and "wait you out." I look forward to watching them go out of business!
This event was so incredibly maddening, the only reason I did not take them to small claims court was that I had to move to the west coast a week later.
