Who called from 2121219949

Thank you, Tator, for this excellent warning! It is one of the main reasons I don't answer numbers I don't recognize.

Similar calls with "Can you hear me OK".  Did not say anything.  Then a real person came on saying something like:  "I was adjusting my headset.............."  BS  Robocall

Received call 4.13.17.  Did not answer.  Origin: NY, USA.  Not certain, but I'm beginning to wonder if calls that list "USA" in the origin might actually be coming from outside the USA; numbers from within the USA usually list city and state only.

also shows "invalid number'

Repeated calls around 4pm.  No one there.  Now Blocked
