Caller type: Unknown
Initially ignored the calls. After googling it and seeing what they wanted, the next time they called on 5/21/2012 I gave a verbal cease and decist from calling again. on 7/28/2012 3 rings and they hung up. I dialed back and quoted the C&D date and informed him if a third call is made to my number they will be guilty of harrassing an officer of the court as I do, in fact, work for the ADA's office in my county. I won't bother with the Florida Department of Ag which handles DNC violations ("charity" solicitations are exempt), I'll just go through my boss straight to a judge and get things handled- very quickly.
post script: anyone ignorant enough to "donate" to a supposed charity that blocks delivery of what should be a legitimate company name should not cry about being parted with their money. Cowardice on this "company's" part to hide behind what they think is annonymity. We soooo CAN find you! Don't believe me? Call me a third time.
