Cuillidh, I understand your frustration it's such a shame they won't allow business numbers on the register. I think your put off is inventive and quite funny, I just find the leaving them hanging on the line very rude and I feel sorry for people needing to work as a telemarketer for a living - it's such a thankless job and they would so rarely come a cross a caller that is happy to talk to them it must be very depressing. Although I don't feel that bad that I engage with them!!!
