Your callers do not maintain this site or this web page. Your callers cannot magically determine which numbers should not be called based on anonymous comments. You cannot expect compliance with your orders until, if possible, you deliver them *directly* to your caller.
Charity calls are commonly placed by a commercial fundraiser, such as Associated Community Services, Dial America, Donor Care Center, Donor Services Group, Harris Direct, Horizon Marketing, InfoCision, Insight Teleservices, MDS, and TeleFund. Like all non-sales calls, these are exempt from federal and state no-call registries, even though the call centers executing the recurring campaigns are very much for-profit and pocket most of what is collected. At times the ''charity'' client is itself a closet profit enterprise, compounding the deception.
As commercial entities, these hired call centers are expected to honor an internal no-call list and add any number upon request. Break that order, the FTC declares, and ''the telemarketer may be subject to a fine of up to $16,000.'' They can also be spanked for excess call abandonment and calling outside default hours.
Because the amounts collected are rather small, these call centers are quite motivated to repeatedly hassle you. The worst of the industry will "reload" a donor multiple times a year, preferring forgetful and easily confused victims. Most if not all such phone farms assume that your no-call order, when given verbally or by keypress, conveniently expires when a client's campaign ends.
In comments from November 2012 and June 2013 linked below, I've discussed simple steps I took to rid myself of a major pain fundraising boiler room by politely rubbing its face in federal laws. You will note that I never rely on verbal cease-communication demands.
