Who called from 8644472132

Same here... called just now and left no message.

I just got a call from this number also.  I didn't answer and was left no message.  When I call the number back it's just a recording saying please press a number (one I think) to be removed from this list and that it may take 24 hours to be deleted.  Obviously a junk call.

Yep, got me too... I didn't recognize it so I didn't answer.

Shows as Not Available here. Called, left no message. Pretty busy in only 2 hrs made all these calls.

just called right now; no v.m.
