Please be very careful this Holiday Season. We have received reports of scammers calling customers claiming to be Commercial National Bank or calling on behalf of the Commercial National Bank, claiming that your debit card has been compromised. They will ask you for your complete card number. Some of these calls have been in person and other calls have been automated. Commercial National Bank and our debit card processor First Data/Star may call you to verify transactions on your debit card, but we will NEVER ask you for your full number or ask you to enter your card number on your phone.
