My mother received a call from this phone number requesting authorization for a charge on our debit card. I immediately called the number back and it was answered by some lady (no company name) alleging she was from the fraud department of the bank. She wanted to know if we had used our Visa debit card at a Walmart in Michigan for $1,600.00 worth of merchandise. I assured her we had not and then questioned her about the bank she represented, the credit card number that was used. etc., She then told me she did not have any of that information. I immediately contacted our bank to see if there were any fraud alerts on our account. There were none. This is a scammer trying to get information regarding your credit card to commit fraud.
