Right I got the car back after discussions that we had with Aylmer guys. Apparently somehow they don't know the Belt got stuck and that how the pulley was ripped from the base braking the triangular bit.
The guy said it might be the tensioner but it can see anything wrong with it.
Anyhow he didn't charge me anything ! but he said I might have to change the tensioner to be on the safe side !
I'd find a new garage firstly their is nothing and I mean nothing that can make the belt get stuck on anything if the pulley sheared off. either they fitted a ****e part. or they fitted a good part so badly. They caused it to fook up. If the tensioner was so faulty that it could somehow cause the belt to throw itself off the pulley then they should have noticed that, when refitting the belt.
You've been bent over, shafted and charged for the privilege. Like I said. Find a decent garage. They sound like a bunch of ripoff cowboys.
they didnt charge you second time around ,which is all that matters we all make mistakes ,its not ripping customer off because of them that makes a decent firm
