I got a call from them, didn't get to my phone in time to answer it, so I called them back. They say they're a "fundraiser for the Florida State Troopers". I said "And you probably keep 90% of the donations, don't you?" He said, "Thank you for calling back.", and hung up.
I suspect my "90%" figure is not accurate... it's probably more like somewhere between 99% to 100%.
I have placed their number into my auto-reject system.
I also received a call from 337-6414 and Fast show on caller id, left no message. Fast stands for Florida assn of science teachers, but if it would have been them that called, they would have left a message, so no clue who it was that called. Real annoying though, since I'm on a do not call list....
