this number keeps trying to fax to my cell

VERY early in the morning - called several times in a row - no message - I am on the "do not call list"
I guess that doesn't work.

Keeps faxing me at all hours of day and night. Is there anything I can do about it?

I DONT WANT THIS NUMBER TO CALL MY BISSNIS

I got two calls this morning at 8:01 am from this number 720-606-7121. The calls were back to back,
I never answer calls from anyone who does not provide info on ID caller, and if they make repeated calls I
RETURN calls right away. I return at least 30 to 80 calls back to back for every call they placed to me.
I do this no mater what the massage is at the other end. That massage box is not full.
I do NOT allow them to see my number. You can control this in you cell phone.
I have unlimited calling and redial.

Got call.  Left message.  Listened to message...beep...beep...beep...beep...end of message.  Got to be a telemarketer or scam artist.  Can't be anything else.

That is not what comes up when you do an Internet search on these slimy slugs.  What comes up is a great many complaints.  They would seem to be major league sleazeballs, violating Federal law as fast as they can go.

Speaking of sleazeballs, since you posted nothing truthful here, you are obviously either a shill, or very careless with your research.  The Internet search results are not as you describe, and entering your phone number, on this site or any other, will get you more unwanted calls, not less.  This site has nothing to do with any caller, and it certainly does not function as a number removal service.

Those with questions about NETPROWA should take a look at these search results and draw their own conclusions: https://startpage.com/do/metasearch.pl?language=english&query=netprowa

This actually does "explain it".

I googled NETPROWA this is what came up:

NetProWa helps people remove their number from unwanted calls and faxes. Enter your line number on this site and the calls will stop.

Guess that explains it!

Caller ID said  NETPROWA  (I don't have the slightest idea who this is!)  I did find a address

NETPROWA.COM
    PO Box 459
    Drums, PA 18222
    US

Most annoying call at 4:57 AM. No message left, just, just a constant beeping noise

This number was faxing and calling my house since 4 a.m. today. When we pick up the reciever, there is no answer. They also keep using 702-606-7051 I interchangeably I believe. We do not know anyone from this area code, so it is an unexpected call, and very annoying.

Called. Didn't answer. Ran my answering machine for a minute or two. No message. Silence.
