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.

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!

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.

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.
(303) 476-9936 - February 18th, 2010 5:00am
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.
(303) 476-9936 - May 20th, 2010 7:19pm
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.
(303) 476-9936 - January 13th, 2010 5:00am

(303) 476-9936 - March 10th, 2010 5:00am
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.
(303) 476-9936 - May 1st, 2010 4:00am
