Do you owe Sallie Mae money?  That's likely your answer...

Received call but did not leave message

Just received call on my cell. No message left and I don't owe money to Sallie Mae....

I called the phone number back and I got a recorded message. It said if I would like to be placed on a "do not call" list I could press one and within 48 hrs I'd be removed from their calling list- Still don't know who it was, but at least they won't be calling me any more.

Recording asking if want reduction on electric bill hold for operator.....
