Received a call. Didn't answer and no message left.

I answered after a few days and they knew my name then immediately hung up. I called back and it said their mailbox was full

Have received several calls from this number for a few days now. I haven't answered any of them because I don't know the number. Anyone out there know?

Received a call from this number, but I don't answer calls for #'s I don't recognize.  No message left.  No plan to call them back.  Tired of the unsolicited calls.  Adding to growing list of dnc offenders in my phone.
