Who called from 4803555800

Keep getting calls from Walden University from this phone number.  I have already told them I am not interested.

Got a call from 4803555800 and they hung up.

I have dealt with Walden University in the past so that is probably who it was.

Yeah, I used to get info from them, but since they don't stop calling and hang up.  I wonder if it is really an university?

David Melstrom at Walden Universtiy.  Psychology Department.  Hes very aggressive.  Yes It is a real University.

I continue to get calls from 480-355-5800.  I have told them repeatedly to stop calling, but it appears "listening and/or applying knowledge" are not skills taught in any of their courses.
