Called our business about credit card fees, blah, blah. Told her we were on the national do not call list....she said that didn't matter because we were on a "registry" of some sort....told he were weren't interested and hung up. She called me back TWICE to berate me about hanging up on her. I told her she should be ashamed of herself for doing what she did for a living and that my next call would be to the attorney general's office.
They are as wicked as warlocks, no doubt about that. But you forgot that the DNC does apply to a business. You'll just have to keep swatting them. It may actually work to tell them your company does not process credit or debit cards, and has no plan to.
