914-339-5684

skyview tech3 called @ 4:35 am from 914- 339- 5694 . They changed their number

They are bill collectors or child support. No one sells at 4am.

They are NYS child support.  When you call them back to enter a fake DNC numbers (and after several times) you get a busy signal.  They see through your fake phone number as a gov't agency can.  Perhaps one maybe might enter the local gestapo number so they can hang up on them at 4am.  
I set my phone to answer in 2 rings on low or I set it to the fax

sleep well, my tortured friends...

They called at 4 am, 6am, 9 am - 1 ring and no one there

Skyview tech 3 must be investigated and their calls to private homes stopped.  What official agency can stop this public annoyance.  They have call repeatedly during the night.   I have no child support and no bills, a reason others have suggested.

I got a call from them at 5:05am. From all of the other middle of the night posts here it seems fairly obvious to me this is an automated telemarketing system trying to find fax machines.to then spam with those stupid travel or medicine spam faxes.

We got a call from this number at 5:36am Skyview Tech3 and a few days ago from a similar number, still Skyview Tech2 at 2:10am 914-339-5655.
