Good thing the CC company has your back.
So, either SM has a serious CC security breach...... or they have a thief working there.
My guess is...... the latter.
I’d be giving them a call for sure.
I wonder how close those two stores are to where the SM warehouse/sales location is?
Of course, to be an in store transaction, they would have had to clone the card.
Did you call, or do the transaction on line?
