well re-reading it, its nothing to do with bobs dad anyway, his son chose not to have it and gave it away, if you give bob, not his dad the money back then everythings tickerty-boo, tell bobs dad to do one, and that hes lucky he got offfered a full refund, he has no leg to stand on, upon purchasing the tickets you was not bound by a verbal/written contract and if he gave the ticket away thats his choice, after thinking bout it you wouldnt even need the recipt or any proof of it, if this went to court the district judge would laugh it out the court, you have down the ground work by offereing refund, he cant have the ticket as its not his, sell the ticket to me and let him come ring me up ahaha
