I had a mechanic come out to repair some emissions on my car he said 11 am came by 1130 am I was told labor would be 76$ it took him one hour. I didn't realize he charged me double until I checked my activity on card. He didn't say anything about additional 1 hour and I signed it completed. I call the 800 number one operater said would call back no such luck. Second operater said we will check it out still waiting for a response back. I like the concept but not when I get the bait and switch happens. Very disappointed.
