The Old Hickory Credit Union has been flooded with phone calls all day Wednesday.
"It started about 9:30 this morning and we've just been bombarded with not only members, but nonmembers," said Bonnette Dawson, the CEO of the credit union.
Dawson says by their best estimate, hundreds of people have been receiving scam phone calls.
The automated message claims to be someone with OHCU, telling people their debit card has been frozen or compromised and they need to "Press 1" to reactivate the card.
Once the person pushes one, a real person on the other end takes over and then you're prompted to give out your card information.
Dawson said they don't know how many people, if any, from their bank gave out information.
But Dawson told Nashville's News 2 if anyone did give out information, they need to call the bank right away.
"It's very frustrating when members call and they think we had something to do with it," explained Dawson. "We didn't and there's no way for us to stop it either, that's the problem."
Dawson said OHCU would never call customers and ask for their information.
"We just don't do that so that's the first clue," said Dawson. "Anytime you get a call like that you should never have to give that information. Ask for a number and call them back if you don't recognize the number."
Dawson said they have been in contact with the Department of Justice, who is aware of the automated phone calls.
