The best way to mess with these people is tell them you'll donate so have them send you a bill then send it back with no money and write on the bill to take you off their list. They get no money and it cost them postage.
I picked up the phone and they said they were involved with children families of fallen police and wanted to send me something in the mail and I told them I was not interested and that was it. Hopefully they will stop calling.
Called and asked for my parents. When I am 23 years old? When I said they must be stupid that I could take the phone call because I am 23 they said [***] you and hung up...very rude!
I've been getting phone calls from this organization for more than a year. One time I did pick up, stupid me, and listened to their speech. I told them I was not interested and hung up. They've started calling again recently. ANNOYING!!!
