So my car developed a squeal from the serpentine belt (drive belt) and so I changed the belt over with a friend who used to be an apprentice mechanic and it didn't fix it. So realising that I don't have the skills to take it further, I took it to the local Jax mechanic.
They said it was my tensioner and pulley and it'll run me $650 which I paid for. This morning the squealing was still there, just the same as before. So I called my friend (ex-apprentice) and he said that there was nothing wrong with the tensioner at most the pulley on the end might have needed a replacement for around $100.
I took it back to Jax and they are saying that they need to have another look at it. But it is probably the one-week-old belt and the tensioner was still needed to be replaced.
Where do I stand? Clearly, if the tensioner was the problem, there wouldn't be an issue now. I doubt I can say I want a full refund. But $650 is no small amount to have paid for something that wasn't the issue. What should I be telling the mechanic?
Mechanic replaces a part, didn't fix the issue, charged a lot. Should I ask for a refund? Or something else?
