That was another reason that we stopped using that mechanic, We'd take a vehicle in to have a simple job done and get it back 2/3 days later. The guy we use now always finishes the job the same day ... and our vehicles have very few problems now. A much better mechanic all round.
Poor organisation that's for sure. The thing is I put it in first thing Wednesday morning and said I was quite happy for them to keep it a few days as long as it was ready for the weekend. To phone on Friday and say they didn't have time to change the belt is a poor show.
Usual excuses of course. 'Oh one of the guys went home at lunch time'
