call is a fax in the middle of the night - 2 times now

call is at 6:00 am picked up no answer annoying that early

Called me today at 8:30 am. Just a high pitched beep on the other end.

Called my cell at 7:30 am - they left a vm full of beeps... I called the number ... NetPro WA?   It said something about "If you are receiving unwanted calls.. leave your number and will remove you."   I'm afraid to leave a number - So, I left them 720-606-7137 ... And, blocked the number via Sprint

6am call!!  720-606-7137 Not much info on their website NetProWA.com, just front page saying they are a service that helps telemarketers filter their databases of Do Not Call numbers and "If you are receiving unwanted calls.. leave your number and will remove you."   I'm afraid to leave a number too
If they're supposed to be filtering databases for Do Not Call numbers, why are they calling those of us already on the national Do Not Call list?
