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 did laugh at the injured Polish Police changing a light bulb. Yes, we continually get calls from them. We told them to mail us info if they wanted something. They still call and are becoming quite rude. Even if we hang up on them they call several times the next day.
I just called that number, blocking my CID and got an answering machine with a male voice on it. I asked to have my number, which I spoke twice, from their calling lists. We'll see what happens.
They phone at all hours without leaving messages....... who are they..........? no bill. taxs paid ? I hate these calls that they repeat and repeat..........
