so my question is if the charges do go thru how likely am I to get the money back ? what are my options? thanks.
You shouldn't have any problems being reimbursed. It happens so often now the bank people are used to dealing with it.
Martha is correct about the EFTA provisions and since you reported the unauthorized use immediately you're covered.
That said, there's a reason I don't have a debit card, only a couple of credit cards and an ATM card. With credit cards one doesn't have the cash flow issues that may arise from a cleaned-out account tied to a debit card.
