The mechanic that accepted my job did not have the experience to correct or diagnose the fault accurately and when I asked for a refund he refused. So I then escalated to ClickMechanic administration and they agreed with me, asking the mechanic to refund my payment in full. The mechanic refused to do this and it turns out that ClickMechanic can't force them to and are unable to refund themselves. So case was closed with no refund. I would suggest you enquire of your mechanic, that he knows how to fix this and that you get it all in writing - without this, you are unlikely to get any refund
