They claim they are from the United Breast Cancer something.  Wanted to send me a pledge envelope.  Repetitively said no and reminded them they are breaking several "Do Not Call" rules.  1st- their phone number is not a real number when you attempt to call the number back it is disconnected.  2nd- Interstate charitable fundraising must comply with the DNC rules as if they were a telemarketer which would probably explain why they are using a 307 number attempting to fund raise in Wyoming.  Report them on the Do Not Call website.
