Received a call from a Nick he asks to verify the my credit card number he had the last four numbers of the card.

Received a call from Nick. He had the last 4 digits to my credit card. He also had my email address and was telling me I was a good credit card customer and he want to enroll me in a plan. I told him I wasn't interested and that was the end of that.

Got 2 calls today, one right after the other. Less than a minute apart. No one on the other end.

I've had 4 calls in the last week and there is no one there.

I get several calls from this number every day.  No one is on the other line or ever answers

two calls today, just hangs up.
