This true, its not a scam as i previously thought.  I had ignored this number for a 2 months and finally decided to answer, low behold, it was regarding my husband's Wal-Mart MasterCard. They informed us that our Mastercard had not been paid and it was past due I had explained to the person that it was on automatic withdrawal but I failed to remember that a few months ago my husband lost his debit bank card and our account was being withdrawn from there to make payments instead of our actual account with a routing number so we got that taken care of. The only thing I didn't do over the phone with that particular Representatives is give them my information regarding our new bank account/ debit card I ended up calling the back of the Walmart card and setting it up myself so I know that I'm talking to a actual person from that company.
