Received a call from this number claiming to be Capital One, calling regarding suspicious activity on my debit card. Told the person I had a bad connection and would need to call back. He gave me a toll free number 800-536-8831, confirmed with Capital One that this is NOT one of there phone numbers. Confirmed that it was a scam call.
Voice mailer claimed to be a rep for the "card/fraud protection" part of Capital One. She made a few "uhs..." as if she was reading from a piece of paper (or the monitor) and almost mixed up the ending reference number. She also gave the phone number 1-800-536-8831. A simple Google search can tell you this is not a legit Capital One phone number. --> http://800notes.com/Phone.aspx/1-800-536-8831
When in doubt, call the actual bank number. This is, otherwise, an official scam. The caller's ID even reads: "VANTIV"
Female voice said she was with the fraud department. Would not tell me what company. She said my card had been blocked. Would not tell me what card. I told her to kiss my [***] and hung up.
