I once had one that called me up. I did not give and then I received a few days later a letter thanking me for my pledge and an evelope for the donation along with an amount circled
This only happened once? It happens to me regularly.
Here’s the problem. The legitimate tzaddakos hire fundraising telemarketing companies. The callers make a commision. There is no option in the software they use to send an envelope with no pledge, so the caller, who wants his commision, marks down a bogus pledge.
I don’t like it, but I’ve learned to be thick skinned and ignore it.
