Hey, before you get all huffy just lemme tell you something about Target receipts...
When you make a return at Target, they usually pay you back in the same form you paid them. For example: You pay for something in cash...you get cash back. You use a check...you get cash back after the check clears. (you get store credit before it clears.) You use a credit card...you get money back on your credit card.
Now let's say you buy a gift, and the person returns it. What good is it for them if YOUR card gets a credit? If it's a gift, usually it's bought by someone else, so there's no need for Target to credit the credit card.
It sounds to me like you're just mad because you didn't think to bring the original receipt.
Not Target...YOU!!! You made a mistake, and now you're complaining about Target, because why? Because you're a whiny baby that's why...
