Pep Boys can blow me

I had about the worst case of blatant attempted ripoff you can possibly imagine with these guys. They knew they were doing it, I even called them out on it, and they still had the audacity to act like I was being unreasonable. Anyway heres the situation.

The heater on my car had stopped working about a week ago so I brought it in to get fixed the other day. Its there about 2 hours and then they call me back and say "We didn't find anything wrong with your heater". Umm, wtf? I guess I imagined driving to and from work 45 minutes each way for 3 days with ice cold air being pumped through my car. This should have set off some kind of alarm in my head telling me to just take it somewhere else, but I never had problems with these guys before so I just shrugged it off and told them to look again.

About an hour later they call me back and tell me they found a hole in my lower Radiator Hose and they would have to replace it. They also say some dirt and stuff got into my coolant so I would need a flush. They say it will cost $220 so I say no problem fix it.

So finally about 6 hours later they call me back, and expecting them to tell me it done, I was quite shocked at what happened next They tell me, in the process of replacing the Radiator Hose, that they "accidentally" punctured a hole in my Radiator so it had to be replaced. I figure "hey accidents happen, as long as they don't charge me for it its ok". Then they say "To replace it is going to bring the total to $660" WHAT THE FUCK!!!!!! So I calmly say "I'm not paying for that, you broke it not me, its your fault so you have to eat the cost". They say "No you have to pay for it" so I tell them not to do anything till I come talk to them.

So the next morning rolls around and I go there to have a little talk with the manager about this little dilemna. He tries to back pedal off the original statement and say it was like that when I brought it in. So after I yell at him for a while they had the fucking nerve to still charge me for the new hose and coolant flush, and did a half ass job putting my car back together so it ended up overheating on the way home.

I just don't get it, why the hell would you risk losing a loyal customer by not even admitting or making up for your own mistake? Had they simply apologized and not charged me for their mistake, I would have been happy and remained a loyal customer. Instead they shit on me and lose me for life over a simple little problem that in reality would have only cost them less than $100. Fuck Pep Boys, they are on my black list now for life.
