It is a phone scam. They call random numbers and a recording say that your credit card has suspicious charges and ask you to confirm your cc number and PIN.

I do not know who called but I received the same missed call.

THIS NUMBER SHOWED UP IN MY MISSED CALLS.  I HAVE GIVEN MY NUMBER TO NO ONE.  THE ONLY PEOPLE WITH MY NUMBER ARE MYSELF AND TRAC PHONE.  WHO IS CALLING FROM THIS NUMBER AND HOW DID THEY GET MY NUMBER?  THEY LEFT NO MESSAGE AND NO NAME SHOWED UP ON CALLER ID.
