Would love to know why they call and can not leave a message

On Thursday, 21Nov2013, received a phone call from 313-483-7603 from Diversified Consulting (or similar name) that is trying to collect a debt to Sprint.

The obnoxious person on the line ignored the fact that I answered with a name other than "Michael Armstrong."

Can you say "scam?"
