Who called from 3100536585

Received call,  female voice.  Asked for me by name... When I said "Yes?".. they hung up.  Thought I heard a call center type of murmur in the background

caller new my name then began singing and using foul language!

Got a call from 1-310-053-6585 and asked for my wife who was not home. I asked if he had a message and said no and would call back. I asked for a company and name and gave the name Brian and said was from Immigration.

hung up before we got to phone

have had several calls but never a voice mail and if I pick up they hang up - what is up with this???
