America's Service Station outrageous charges, mis-diagnosis, work not performed but charged Canton Georgia

Went in on a Friday to have brakes, and service engine light looked at, as well, change of oil and if alignment was needed on my work van. Shop called me in the evening, and $1400 latter(super duper tune-up, complete brake job, wires, plugs, fuel injection clean), was told everything was good to go. The following Monday, got it on the road and in the first 5 minutes, service engine light on again. When I finished my service call, noticed antifreeze under the van which I've never had a leak before. Took it back and told them that I never had a leak before and if I had, I would have told them '"hey my radiator leaks, fix that also". So, one of the managers said, well, maybe we could have hit it or something, so we'll fix it. I left, and the next morning another manager said, "we can't fix that, the other guy is new and it's obvious this things been leaking for 6 months, but I'll work with you on the price.....$700+....it's a bear to change, you gotta take off the front, etc., etc."....well, I said, don't worry, I'll change it myself...$240 for the part and an hour to change it...When I changed it, noticed that they hadn't even changed the oil...same dirty filter...so I went back, and a few appologies later, left and of course, service engine light on again...next diagnosis, need ignition coil replaced....$277 for a $100 part and 8 minute change out(also wrong diagnosis). Then, still check engine light, so I took it to Advanced just to get reading to see code....misfire on 6....so, took it back...and they supposedly tested..."oh, you got water getting in there, need to replace upper and lower gaskets and that will definitely fix it!" and that's only $750 but I'll take off and hour...so, fought back and forth, and agreed to go in half if that was going to fix the problem...well, you know the answer to that...didn't fix...so next diagnosis, "I think he probably broke a fuel injector when he put it back together, it happens, but we'll get it fixed tomorrow"...well, again...NOT....then, manager gives me $0 invoice for that repair..thanks...so then, go in the next day...and...."wow, your water pump is leaking water"..blah, blah, blah....so finally got in touch with owner, and went round and round, ( they wanted me to come pick up my van with a tow truck, didn't want to work on it any more )....so he finally agreed to fix the pump and take it to another store to find out about the check engine light(admitted that his techs there aren't really qualified and that I would see new faces next time I went in for oil change)...well, get call from manager..."you won't believe this but it was the fuel injector, we must of got a bad one when we changed it the first time"...needless to say....DON'T GO TO ANY OF THESE SHOPS....PS...WHILE SITTING IN WAITING ROOM VARIOUS TIMES OVER THE 2 WEEKS, SAME STORY FOR MANY CUSTOMERS...COME IN WITH MINOR ISSUE...THEN, YOU NEED A $2000 REPAIR, ETC, ETC.....ALSO....NOW MY SERPENTINE BELT IS SHREDDING, DUE TO REPAIR OF PUMP, SCREW VISIBLY NOT INSTALLED TO HOLD PART IN PLACE WHERE BELT IS RUNNING....THIS FRANCHISE NEEDS TO BE CLOSED!!!!.
