After posting my initial review I was contacted by the manager, Bob, of the Sahara Rainbow location as well as by the district manager Shayne. I was pleasantly surprised by the response to my review. In attempt to rectify the issue, Bob apologized on behalf of his store and asked if we would bring in the vehicle for him to look at. He offered to refund us the amount we paid the other mechanic to fix our air conditioning. We took my vehicle in on Saturday and Bob and a mechanic looked at the vehicle. As previously stated, my husband and I are not car savvy. We would expect if a new part is installed next to older parts it would be a black and white difference. Although we couldn't tell the difference, Bob did insure that a new part was ordered and attempted to make it right by us. We appreciate them reaching out and thought this showed professional service.
