Who called from 7206067063

My answering machine recorded a fax machine beeping, and caller id was 'NETPROWA'.  Ironically, if you go to their website it says they remove your number from unwanted calls and faxes!  So, why are they trying to fax me at a voice number?

They are faxing you at a voice number cause a bunch of boiler room wimps must've spoofed their fax number to harass you? That must be it. Block this number and if you get another call, it's confirmed that the calls are coming from a rotten boiler room.

They're trying to fax me too and I found their website to "unlist" your number.  Jerks.  So annoying and I wish I could get it to stop.

Tired of fax calls from 720-606-7063. Don not have a fax machine.

Fax call came exactly at 7:00 am CST..
Then again, follow-up at 7:05 - had to disconnect
the cord from Anwering Machine.. The phone
Number had been scrapped from Local Business
Phone directory, where it was registered a few
Days ago. They, telebarketers, waisting no time
to start bombarding you with the fax offers..
