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

2010-02-18 by Call them back! Here's the info!!!
I have tracked down Mainstream Marketing Services from Boulder, CO. Their headquarters are 5620 Arapahoe 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 hundreds 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 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 HELLO's and no response, it seemed to go dead. Not exactly a hang-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 hang 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!
