Fraudulent phone call about Debit Cards

Just a Heads up just received a call from a computer stating they were calling from the fraud dept from my Bank which is First Northern don't think that matters though . Anyways the computer said my debit card has been frozen/locked and to have it unlocked I needed to type in my 16 digit card number . That didn't sound right to me so I hung up and called the bank and they verified that it was NOT THEM AND THAT WAS A FRAUDULENT ATMEPT TO GET MY ACCT INFO !!! So just so you know if this happens call and report it I also reported it to the Dixon PD . The bank said if it was them they would only ask for the last four numbers on the card !!! Hope this saves someone a whole lot of headaches down the road ...
