They had my car for two weeks when supposed to be done in 3 days. Then when I inspect my car I find a broken hood bumper and a chip in my windshield that wasn’t there when I dropped off my car. So I had to bring my car back to get the replacement bumper and have my windshield replaced.

Our vehicle is still leaking water from the anc and now we have to bring it back . The mold smell is still there as well so there’s no telling what the water damage actually did. Now we have to take more time off work /school to bring the vehicle back that we told was fixed.
