Who called from 2012660022

I keep getting calls from this number, and from a Hackensack, NJ number that's similar.  I never answer it, but it's getting very annoying.  This has to stop.  Why do people do this?

I received several calls from this number, nobody responds when I say hello, but they continue to call every couple of hours.

i have been reciveing calls from 201-266-0022 for about a month.

same as above. This number has called my house 5 times today.

what is this number?? it has called me so many times today. i just let the phone ring. it rings and rings for mintues at a time. then call back 10-15 min later. who in the hell is it? then the my phone rings again a few hours later. i just added my number to the do not call list, so maybe this will stop it. they havent called me cell yet.
