Same here

Called my business numerous times.  Won't speak after my introduction.  Won't hang-up?

Some kind of "energy conservation" company touting reports that you can get $3900.00 in government credits for becoming more conservative in your energy use. Located in central Florida, would not give physical location for security reasons. Called my place of business 3 times 5/19/10. On 3rd call I asked to be removed from call list and was assured I would be. Then they called again today.

This has come three times to my cell phone number, which I have put on the "Do Not Call" list.  It begins by saying "Please do not hang up, this is a public service announcement" -- but then, of course, I hang up.

DO NOT HANG UP.
