Here is the FTC law about telemarketers calling on behalf of charities - it's not legal for them to keep calling:
Charities are not covered by the requirements of the national registry. However, if a third-party telemarketer is calling on behalf of a charity, a consumer may ask not to receive any more calls from, or on behalf of, that specific charity. If a third-party telemarketer calls again on behalf of that charity, the telemarketer may be subject to a fine of up to $16,000.
I've recorded 8 different phone numbers that this telemarketing organization has called me from in the last week, sometimes we get three calls a day.
