My parents were involved in a dent removal scam. They were approached by a guy who said that he could fix the dents in their car. He did partial work, so my parents paid him $450, and he said he was going to come back to finish the rest, but of course he didn't. The phone number he gave was bogus too. So, they put a stop payment on the check. But he already cashed it at a Money Mart place. Now, the Money Mart has been calling and harrassing them to pay the $450 plus the stop payment fee of $25. The Money Mart is threatening my parents that they will sue them for that amount until they pay according to the UCC section 3302 letter that they received from them. Is that true? Does the third party have a right to sue my parents when its between my parents & that guy who provided fraudulent services?
