Credit cards do not have overdraft fees. Is this a debit card that withdraws the money from a checking account? If so, you may have charged something before tearing up the card that didn’t clear your account until later. You can ask for a statement of charges (or wait until the regular statement comes out, but sooner is better when disputing charges) and verify that you made the charge or dispute that it was not made by you. If it was not made by you, they should remove the charge. You may have to request separately that they remove any overdraft charges if they don’t do it along with the other charge.
