Integrity Automotive Service Inc

I had been going to this shop for 15 years.  Until recently (last 6 years) they have been great.  Last year I was charged $2,700.00 for a brake repair and a 60,000 tune up and some mystery belt and hose repair due to "rodent damage".  Recently I returned because the car wasn't starting correctly and using excess fuel.  They charged me $130.00 for a diagnostic and an oil change I asked them NOT to do.  I drove my car to the dealer who found the air filter compartment left open. The dealer has since found belts that were never changed, and re-programmed my car's computer at no cost.  The dealer reviewed my work order (which was missing some important information that Integrity could NOT  print out for me because the computer wasn't working) from Integrity and said I was over-charged 100-125%.  The last visit to Integrity I was told my car had a blown head gasket and needed a new engine, but the dealer found the car to be in perfect working order except for the open air filter compartment.  This place is full of incompetent, lying scammers.  If you have money to toss away, give it to them, but take your car else where if you want it fixed.  One star is one too many.  AAA certified?  I think not.
