Suspected hack of my pogo account

I reeived "pogo mail" that warned me that my account was under threat of suspension. That notice included a phone number [Unauthorized - Removed] for me to call to mediate the situation. I called that number and was greeted by a heavily accented female voice which I believe to be a real person. She claimed to be Pogo team support. I asked her to convince me that she was indeed representing Pogo. The line went dead.

Is the number legitimate?
