Who is this, they keep calling and hanging up

they are unprofessional, obnoxious, demeaning callers who solicit money for various 'charities'. best i can determine the call center or at least the mailing address for sending money is in boulder, co.

Just a follow up

I called the 1-866-206-5936 listed above, and got the recording,

"the number you have dialed is not in service at this time"  

This must be completely bogus.

I called the number back and got a message claiming to be "millenium fund raising" for Children's Cancer Assistance Network.  When googling millenium fund raising, what I find is that MFS is a software for raising charitable funds.  What I find when I google "Children's Cancer Assistance Network" is

Childrens Cancer Assistance Network
3110 Judson Street, # 186
Gig Harbor, WA 98335-1254

Phone:1-866-206-5936

I will be calling them to complain about the tactics they are using and I suggest everyone else to the same.

Calls and hangs up when we answer

This number has called our home every day for the last three months. Usually if we pick up the line- no one answers. Twice they have stated they are raising money for a Children's Hospital Fund- but are unprofessional and unwilling to give specific details. We have also heard laughter in the background.

Normally calls and hangs up whenever someone answers.  This time stayed on the line (sounded like a call center in the background) with laughter for a second before hanging up.

Random calls at various times throughout the day and
evening.  At least two calls a day.

Called for my older daughter,said she had and ad in the paper for a pool-boy.
