In reply to wilkie14c:
Awful. Many charities are guilty of pestering previous donors.
I've had it time and time again. Make a donation and they've got you on their records as a "soft" touch. Some of the cancer research charities are the worst.
Having got you they phone you and try to weedle more out of you and make you feel guilty for not making further donations.
It's shameful behaviour, particularly where the donor is elderly.
