While on vacay, I bought MOs at an unknown to me WM. I used two VGCs which were both approved after I swiped them and saw the receipt print BUT no $1K MO printed. I asked cashier to let me look at the receipt and she handed it to me. It says there at the bottom CHANGE: $1000.70
She called the supervisor who obviously didn't know how to handle it but I was 100% sure they should give me my money back since it has already been taken out of my cards. I called to check my balance and they were zero on both cards. THAT plus the receipt printed and indicated change of $1000.70 meant that I shouldn't leave w/o settling the issue or else, I'm out the full amount and will have to go back to that branch later when they find out later. NO way would I agree to go back later till they figure it out since it was clear to me that I was owed a refund. I stayed calm all these time since I knew I was right.
I asked for a cash dept manager who, fortunately, understood it the way I did and asked them to check the machine to find out why it didn't print the MO (if it printed, then just give me the $1K MO) OR if it's broke, they have to give me refund of $1000.70 in cash. Soon as they re-booted the machine, the supervisor keyed in something for the payment and the MO printed. I was so relieved to get out of there with issue resolved.
For those who experience the same thing in unknown territories, make sure the issue is resolved before you leave and don't just take their word that funds will go back to card especially IF you saw a receipt print which means the transaction went through. If that's the case, funds will not go back to card(s) and if you inspect the receipt, I bet it'll say change is due if no MO prints.
