Not what was requested

After having my vehicle for two days S & J Auto repaired and charged me ($130 over the original quote) for an unrelated problem because as I was driving away from their shop the exact same issue persisted. I returned the very next day and within 5 minutes they said oh, it's this problem and wanted to charge me again for something else. When I tried to compromise by agreeing to pay for the part if they waived the labor, they refused. Not only is the quality of their work poor, so is their quality assurance and customer relations. (The reason one star was selected was because this site forced me to pick one.)
