Cottman Transmission COTTMAN TRANSMISSION NEW CASTLE DELAWARE RIPPED ME OFF DO NOT GO THERE New Castle Delaware

 I took my car to Firestone for an issue and they told me that it was a transmission issue and suggested Benchmark.  I figured I would take it to Cottman, because I felt I was more familiar with their name and that I would get an honest experience backed with a brand name.  WAS I WRONG!!! I was encountered with Mark Testa who is the manager at this location...I told him the problem with my vehicle and he said leave it overnight and he would recreate the problem and be able to diagnose what is going on.  I waited most of the day and he called me saying, well I really believe all it needs is a tune up and though I am not certain, I believe that if you get the tune up it will fix your problem.  (TALKING OUT OF BOTH SIDES OF HIS MOUTH!!!) So I askes how much is the tune up, he says $493.91.  I said well since you are a MECHANIC and you really strongly feel that the tune up will fix my problem go head and get er done!!! He fixes it, and I pick up my vehicle to find that same problem still occuring now also when stopping in traffic, the car stalls while in gear as well now.  I take the car back the EXACT next day after payin $493.91 for the tune up and after having my car from 8 when they open to 4:30 when I received the call, Mark explains NOW that my car needs to have the transmission rebuilt and it would be a whopping $2300.  I explained to Mark that had he found the REAL problem in the beginning I would not have paid $493.91 for a TUNE UP.  I took my car to a TRANSMISSION SPECIALIST for him to diagnose an ENGINE PERFORMANCE PROBLEM for it only to acutally be a TRANSMISSION ISSUE.  My car is not worth me paying $2300 for a transmission and he stated he would not refund me ANY of my money that was spent for his misdiagnosis.  Waiting for the owner Gregory Dipliner to respond to my customer complaint.  Will take this to every length to get rectified.  THEY ARE UNTRUSTWORTHY!!!!
