Card member services

This number keep on calling but does not leave any messages. So, I figure it is not important. If it is important they will call back.

caller didn't leave a message, but calls lots at any hour of the day.

I called this number back and spoke with a lady who wouldn't tell me who they were or why they called me (twice) and she then asked for my first and last name as well as my social security number....yeah, DO NOT answer their call because it could be some kind of scam.

The number was from US Bank Collections Dept.
