Who called from 2132102523

The robo-call machine listened to my voice mail greeting, and then hung up.

Rang several times.  When I answered, before I said anything and without pressing any numbers, I heard the a robocall recorded message saying "your request to be removed from our call list will be processed immediately".  I simply hung up.
