Who called from 3472183944

Called at 9:30 pm in the Northeast from Cardholder services offering to lower my interest rate.  When I pressed "1" to speak with an operator I was connected and said I was put through because it was late at night and I wanted to be taken off the list.  The operator hung up on me.

This number called my phone and when I answered no one responded.
