Who called from 2126596473

I CHECKED AND THIS NUMBER IS NOT IN SERVICE. HOW DO THEY GET SUCH A NUMBER TO BE SHOWED AS THE CALLING PHONE? I COULD NOT EVEN UNDERSTAND THE ACCENT, SOUNDED LIKE FROM AN AFRICAN SPEAKER.

I refuse to answer my direct dial simply because I did not recognize the phone number. It is a sad situation with all of this random phone dialing.

Stop the harassing.
please

Called multiple times and left no message.  Also non native english speaker gutteral tones in background.

I just received a call from this #, 212-659-6473.  I did not answer because I did not recognize the #.  When I call back I received an automated msg stated the # is not in service to check the # and try again.  I checked the #, called again and got the same results.  How can I get these people to stop calling as this was not the first time I received calls from this # and they never leave messages.
