A verbal demand to shut up will not stick anyway. The dirty secret is that the calls are placed by a commercial fundraiser, such as Associated Community Services, Dial America, Donor Services Group, Harris, InfoCision, MDS, and TeleFund. March of Dimes has been a repeat client of InfoCision every Autumn, but this may not be an exclusive deal.
Still the calls are exempt from federal DNC under the charity status, even though such call centers are very much for-profit and pocket most of what these periodic campaigns collect. At times the ''charity'' client is itself a closet profit enterprise, compounding the deception. However, 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 are also covered to a point by other regulations for telepests, so you can kvetch about abandoned calls, bot calls to mobile phones, and so on.
What else to do? File complaints with the FTC and attorneys general, and the charity group doing the hiring. When the boiler room calls, try getting on a master ''no-call'' list for all of that firm's charity clients. (See more discussion under this number: 901-881-9984 ) If a given commercial fundraiser seems deaf to your demands, and/or merely renews its pestering with the next campaign, turn up your volume on paper. Send a cease-comm notice via USPS Certified with return card. It need not say more than to stop calling and writing whatever numbers and addresses you want protected. With InfoCision I would not wait, but shoot that letter out right away.
