Yes, you should call back immediately with your pertinent details, confirm your SSN#, Bank Accounts (For Garnishment),
and Date of Birth. That is the only way you may stave off the IRS from attacking you.

DO NOT CALL BACK. This is a scam designed to part you and your money. the IRS would NEVER call you. If there is an issue, the will send you a letter via U.S. Mail.
