Who called from 3231647558

Called at the same time the last two days and leaves no message.  Caller ID shows "Name Not Found."

Also received a call from this number and when I answered I got no answer. I tried calling it back and
"the call could not be completed as dialed." ??? :-/

Keep getting phone calls from this number. Never answered until today and caller was looking for a Nelson? sounded like a collection agency

Name Not Found.  They rang and waited until my machine picked up before they hung up.

These bozos just called me and did not leave a message.  I have been on the Do Not Call List for years.   Will report to FTC.
