The people were nice but after going in for an AC check, apparently the mechanic checked my engine filter and didn't put it back on right so I had to make 2 trips back so they could figure out why my car had no power when accelerating and it was louder than normal. I spent an extra hour and a half there trying to get the issue fixed that turned out to be negligence when the mechanic didn't replace the cover to the engine filter properly. Time was lost but the final mechanic took extra time to make sure that the cover was put on properly but the clip to the cover is still broken
