Business ProfileforRev DIY Automotive Repair

I went to Rev DIY on for an oil change and free mother's day diagnostic 5/24. Upon leaving my vehicle was running very rough, and it was NOT running like that when I arrived there. I pulled over, tried to call, shop had already closed. I returned next morning, ****** was rude & defensive before I even spoke to her. My husband asked what was, why the vehicle was running so rough. The owner said the vehicle was now missing on four cylinders & needed a 4 hour electrical diagnosis due to an electrical issue not a mechanical one. He said it was fine to drive. We took it home and returned same day, leaving our vehicle until the following week. On 5/30, we were called and told the diagnosis showed no electrical problems, but that now we needed a new motor, for $5000.. They had also performed mechanical repair, without authorization, and charged us for that, even though it was not indicated in either diagnosis. We paid for the 4 hour electrical diagnosis and the mechanical repair (gasket replacement) so we could get our vehicle towed to another shop, where the vehicle was repaired for $160. It only need two oxygen sensors, which showed up in BOTH the diagnostic tests ran by REV. We asked repeatedly for copies of our bills and were ignored. When my husband went into the REV to talk to the owner, the clerk **** ***** threatened to call the police if he didn't leave the office. The owner refused to speak to him. The bills also show the wrong license plate and mileage. EVEN WORK ON MY CAR? Rev automotive charged us $354 for an unnecessary electrical diagnosis, and $191 to replace the gasket that was not indicated by either diagnosis. They did NOT do the necessary replacement of the oxygen sensors which actually was indicated by the FIRST diagnostic and which actually repaired the vehicle. Instead, they overcharged us for an unauthorized and unnecessary mechanical repair, and an unnecessary second diagnostic, and tried to scam us out of a $5000 new motor which was not needed.
