called a number on do not call list. was a fax number did not break connection for over a minute. very annoying, then 72 hours to remove number, unacceptable

Frequent fax calls from 720-358-6024 - NetProCo

Netpro faxing my house weekly as this is a private residence. No faxes here. Please remove my number from your list.

I receive at least a call per day from these idiots, despite being on the Do Not Call list.  I finally called the Federal Trade Commission.  Their number is 1-877-382-4357.  They only act if there are numerous complaints against a company, so call the FTC now to stop this harassment.

if you don't stop calling,Im going to sue you!!!!!!!!!!!

I would very much appreciate if you would stop the relentless fax calls from you.This is a private home phone. Becoming very bothersome. So PLEASE STOP!!!!!! The # you are calling is 2565233226. My wife is in a wheel chair and tis makes it very difficult for her when i am not here. THANK YOU!

Called twice so far - just beeping on the other end.  I am hoping it doesn't escalate to morning calls!

FAX

I get the constant calls from them at Netproco but it comes from 720-452-0047
yes we want it to stop, several times a day

Just take all your junk mail and fax back to them.  I have a collection of about 200 faxes from them over the last 2 months that I send them all back every time they send me more junk.  I also add  junk mail to the pile, sales ads from grocery stores and send them back every time I get a fax from them.  If everyone did this then we would tie up their fax machines and they won't be able to pester us.

NETPRO IS ANNOYING CALL WILL YOU BLOCK THIS FROM MY IP ADDRESS THE NUMBER IS 720-452-0008

We receive a minimum of two calls per day that turn out to be fax

Caller ID says Netproco. Number is 720-452-0066 trying to send a fax. we keep our fax # yurned off. You would think they would get the message when none of there faxes can go thru

Yes, we receive calls from NETPROCO a lot.  I have found that you cannot call that number to leave a message, nor can you fax them a letter to stop calling. Has anyone figured out a way to stop this? Has anyone ever traced tis number to a physical location?

You need to stop calling as this is driving the administrator crazy.

I am tired of the fax line calling me the number I get is 720-452-0016. I often let the phone ring. There has got to be a way to stop this. Will contact ATT and see what we can do.

My call came from a fax machine at netpro (and I didn't capitalize it on purpose - I have no respect for them!).  The number they used on me was 720-452-0089

Who is this?

Netproco has been calling my number for months at all times of the day,this is extremely annoying and bothersome

Constantly getting fax calls from netproco.  I wish someone would realize that this is a private residence not a business.

have been getting calls for past week from something shows up as netproco under the phone number 720-452-0048  No one is there when answered and it allows to ring till answering machine picks up then just beeps till machine quits.

At my business we have been receiving irritating phone calls from this company for over a year and FINALLY were able to pin down the name of the company: NetProCo out of Colorado. The calls are a nuisance more than anything, beeping, that's it, but they happen almost every day. With a bit of research here's what I have been able to find out: these types of calls are called "War Dialing" and are a way to determine weather the dialed number can recieve faxes for bulk or spam faxing. [I will also note that hackers use a form of War Dialing to call computer modems in order to try and find out passwords and other personal information.] From what I read on NetProCo's website this coincides with the services their business offers. War Dialing in and of itself is not against the law on a Federal level, however city and or state laws may have passed legislation in an attempt to squash - often worded as: "... a call cannot be made without the intent of communicating with a person". However, the fact that NetProCo is dailing the same numbers multiple times and is trying to charge the consumer to stop the calls and/or faxes [info I have derived from others comments on this site] is no doubt a legal gray area. I have filed a complaint with the Federal Communications Commission (FCC) and the State of Colorado Attorney Generals Office and encourage everyone else to do the same. I agree with an earlier comment that while NetProCo's website does allow you to enter your phone number to supposedly stop calls within 72 hours, I wouldn't trust giving them any personal and/or business information.

These jerks keep trying to fax to my home phone-I'm getting six or more calls a day-the fax number that is calling is 7204520081

Is there any way we can find out who is responsible at this company, find out their home phone number and call them at 6am, like they are doing to me?

I keep getting fax from the above number, sometimes at sleeping hours. I don't have a fax and they use my home phone.  Please help.  I am 83 yrs and need my peace from these intrusive calls.

Report them to the FCC!! If we all do it then maybe something can be done so that they stop harassing us!

Calls coming in serveral times a day, no one on other end.  Please stop these calls.

your calls are not solicited for. don't call again

this netproco has been calling my house for over a year. sometimes as much as six times a day.they should be stoped.
