I have received call after call from this number as well. I don't even have a bank account, and this is a brand new phone. I accidentally answered once and they kept asking for someone( couldn't understand the accent and they were very quiet), and then they just hung up.
They called me yesterday (Mother's Day) 4 times and never leaving a message! They called at:3:46,3:35,3:11,3:32! I do have a Credit One card, but it's not over-due at all, and if this company was on the up-and-up, and calling one to remind them of a late payment, wouldn't they leave a voice mail? You would think, and so would I, so this leaves me to agree that this is something BESIDES Credit One! I blocked them after the fourth time. I was trying to enjoy being with my grown sons! Booooo!!
