I keep getting calls from this number but don't answer since I don't recognize the number. I missed a call on 12/10/14 and decided to call back. They claim they are with credit one bank and need my account number to pull up account. I hung up and called the number on back of my card, they have no record of trying to contact me and told me not to give out any info. I called 815# back and explained this. The lady was very rude and didn't like me questioning her. SCAM!
