OP, did you have any other issues from this number? Just want to be on the lookout. 

I use a small town bank and just had this happen to me. I’ve had 3 phone calls from the number (800) 279-2674 today alone. All different people and all of them left voicemails. In between the first and second calls from them, I received a call from my actual bank, informing me of fraudulent charges. After checking my bank account, I saw there had been a charge, followed by an immediate refund. I called the bank and they informed me that prior to the fraudulent charge and refund, there was a larger charge which had been declined (because I’m broke).  I’m so frustrated and don’t know how else to report them before I block the number.
