Who called from 2016934434

I just received three phone calls from this number.  Also, I've gotten several hangups on another number within the last two weeks.  Same company.  When I call this number back it doesn't even ring.  Makes me think it's an auto dialer doing the phone calling.

I've been getting these phone calls from 201-693-4434 the past two days.  I've gotten several hangups on a different number.  I did call Level 3 Communications which is based out of Denver.  This is a legtimate company.  They sell phone numbers to businesses for fiber.  They are a local telephone company. I'm checking into Ad-base systems inc.  Ad-base systems is the company who is buying these telphone numbers.

I just spoke to a person at Ad-Based which is located in Pittsburg, PA.  The man said he was going to see if he can get this phone number and other phone numbers disconnected or investigate why everyone is getting the hangup calls.

Several calls from 201-693-4434 ... they don't say anything when I answer the phone & hang up ....
They don't have anything better to do???

This number calls me like 5 times a day! I don't answer numbers I don't know! If they really need to talk to me they need to leave me a detailed message!
