This guy I met and went out w a couple of times had given me a couple pairs of jeans as a gift. Well they didnt fit right so i took one pair bk to the store for an exchange and the second pair i ended up taking bk as well and exchanged for a pair that fit and the difference was put on a gift card. Well i went to use the gift card and it had a zero balance and they sd its being investigated by loss prevention. What should i do because i wasnt aware of anything illegal when i accepted my gift.
