Umansky jchrysler Dodge Jeep dealership

my Jeep was stuck in 3rd gear so I went into the nearest Jeep dealership which was Umansky's in Charlottesville, VA for assistance. I paid $139.00 for a diagnostic. The mechanic stated my battery was leaking and caused the "inhibertor switch" to short out. I purchased this part from another dealership which I had to drive to (stuck in 3rd gear) which was in Richmond, VA
because Umansky's did not have the needed part. Umansky's repair bill totaled $1,500 plus $140.00 for the part they said was needed however, this part was slightly bent down and when we put it back up in place, the car was miraculously repaired. It is my belief that this mechanic either tweeted the part down or just has no clue what he is doing? In any case, there was nothing wrong with my car. Umansky's fabricated a repair bill of $1,640.00 for nothing! I have emailed and phoned both the General manager, Shannon and the president, Greg of Umansky's with all the proof of this scam and have received absolutely, no reply. DO NOT take your vehicle into this fradulent establishment
