(303) 476-9936

If you're getting calls and no one is there when you answer, it means that the company is using a predictive dialing system, which calls several #'s at a time, and when one of the #'s answers, the dialer "****s up" on the other #'s. In other words, there is not a human being who is ****ing up on you.

Never leaves a message

The caller ID used to say "Boulder" but now it says "Denver" - same nonsense.

Calls even though my landline is on the Do Not Call list

When called the # the message said that I owed them no money. No debt has to be paid. UMMMMM I don't have any accts in that area. Who are these people and why are they calling. Unlisted eh, sounds like a scam.

They asked for someone by their first name only.  When I asked them who they were, there was only silence so I ***g up.  This has happened before with other numbers as well.

I have tracked down Mainstream Marketing Services from Boulder, CO. Their headquarters are 5620 Arapa*** Ave Apt 218, Boulder, CO 80303-1348. Their phone number is (303)415-9830. I spoke with someone named Amanda and told her that this place needed to stop calling me immediately.  She took down my number, said she'd enter it as a Do Not Call into their databases (they have ***dreds she said) and it should take about 7 days for the request to cycle through and to stop receiving their calls.  We'll see what happens.  Even it I'm still called, now I can call them back directly to demand compliance with not calling, or in the alternative...a class action suit?  Good luck with your individual endeavors to get them from stop calling.  I hope this helps.

GOT IT!! I called them back, spoke to Heather.  She states they are a 3rd party company that cold calls people on behalf of "allstate" for free quotes.  They get your # by a multi internet grab bag style of sear****g.  I asked to be removed from their call list and added to the do not call.  Heather said she would.  Cross your fingers.

I called it back and it went to a non-working voicemail system.  Do you have any further information regarding them?

Answered the call, no one was there.  I called it back and it went to a non-working phone#.  The caller ID'd it as a "Boulder Call"

This number "Boulder Colorado" has been calling me for months, and several times a day....now down to about once or twice a week maybe. I can't stand it, even though I am usually not home. Today I was home, answered and after two*****O's and no response, it seemed to go dead. Not exactly a ****-up sound, just a disconnect sound. It also sounded like overseas type or long distance (more than just states away) more like a different country. That is just my experience. I would like these to stop, and don't have a way to block on my phone.

Dear "Employee", Yeah you may be doing your job, however you are just about the most annoying type of person out there. You are not saving me any money by harassing me. In fact I am more apt to **** up on you in the first few seconds due to your guerrilla tactics. Also, instead of spending your time calling people, why don't you go back to school and finish your education. I found several misspelled words and well as sentences that had grammatical errors. Since you have access to our home numbers, how about you give us yours and we will call you at all hours of the day, when you are tired, or when you are trying to put your kids down to sleep. I dare you, give us your number and lets see how much you enjoy! Have a great day!

This number calls our house once per week.I called back once and a man answered and said I had the wrong number and ***g up.then called back and it was a voice ma****e.

this number keep call every night no one there when i say*****o please tale me off youe list. T9R2

these people call you and don't talk. when you call back you get a ma****e. i left a message saying i would call my attorny if they didn't stop harrassing me. we'll see

I've received numerous calls each day from this number. When I answer, no one is on the other line. Today was the first time ever that someone was on the other line, and when I told them I didn't appreciate them calling so much and to remove my number, they ***g up without any acknowledgement.

Asked for a person and I said he was not here then this guy got very smart with me

Has called multiple times a day for the past week or so. Today was the first time I tried to answer and no one responded to my*****o. What is this?

Has called 17 times this week, no message. When I do answer no response on the other end.

He is calling and is not eveing leaving any message had been calling almost twice a week.

I was already on the do not call list for almost a year and still go this. My phone provider gave me the # too and when I got thru they wont give any info to you except we can pass it on to out IT and it'll take time to get you on our dnc~ hmmmmmm She also refused to tell em whom,what,etc they do and whom for.

they keep calling me and never respond when i say*****o! ***

The evening of October 5, I wasn't home but noticed that a "missed call" was on my caller ID.  Checked the directory and noticed this number listed as a Boulder Call.  I tried to file a compliant with the Do Not Call registery but my number had to be listed for 31 days.  I appreicate other people's comments and will pay more attenetion and watch for this number.

I called the 1-800 number and told them to put my number on the DNC list and that is all I had to do.Thank You
