Aamco Transmissions Quote one price for repair then raise the price Mesa, Arizona

Called and was told that a repair of my transmission would be between 1500 - 1800 which included the 900.00 diagnostics. The price depended on if we wanted a 12, 24 or 36 month warranty. Made appointment for 8am Saturday. Was told that the diagnostics and repair would take 3 days. Contacted them on Tuesday morning after not hearing from them on Monday and was told that they just started working on it. Called them in the afternoon and was told that the repair would cost 2100.00 and that was only the 12 month warranty.

They know that once you have to pay them 900.00 you won't take it somewhere else and have to pay an additional 1500-1800 to do the repair. I feel this is a bait and switch deal. The only reason I went with them was because they are a nationwide company. You expect this type of shady deal from a back yard mechanic not a national company. I am just sick because the truck isn't worth 2100.00 and now I can't afford to take it somewhere else and I can't pay my mortgage because I have to pay them an additional 300.00 I had not budgeted for. Bad business practice. Not honest.
