I reversed into a motor bike causing some damage agreed with owner not to go through insurance as there wasnt much damage as soon as he got quote for fixing bike (which was nearky a week later) i gave him the go ahead to get bike repaired. Within 24 hours of him letting me know bike was ready i went up to the garage and paid the bill only to find out he had added xtras to my bill that were not crash damage but he had told garage i said it was ok which i did not, the garage took it up with him and he said to take it off the bill which was fine but he told the garage on the phone that he didnt think i would get copy of final invoice. Now garage bill has been settled he is now after travelling expenses which was never mentioned before until he was caught adding items to the garage bill what should i do now?
