Take your dive alert, hook it up to a tank. When one of them calls ask them to hold a minute and to listen carefully as you tend to speak softly. Put your earplugs in and let rip with the DA. THey will not call you back. Also just got one of those goofy emails about how some cell providers may sell your number to these dirtbags. Anyone else here about this. ANd I'd not put telemarketers in the same category as prostitutes. A good hooker provides a necessary service with no hassles as long as your careful. Nothing at all useful about a telemarketer.
