My mechanic turned in my auto heads on Saturday. I've been chasing them every since. I was promised completion by Monday. On Monday, I was told call back on Tuesday. On Tuesday, I was promised Wednesday. Reason, they had a lot of work. On Wednesday, I was told heads weren't cracked but needed special parts, which they had ordered and would be ready Thursday. On Thursday, I was promised Friday. On Friday, I was guaranteed Monday. On Monday, I was told that the special parts order hadn't been placed and would be ready on Tuesday. Obviously their word doesn't mean much and makes me question the quality of their work.
