Although I would question the validity of a billion dollar scam (as another user points out most plans get free minutes and if you exceed your quota by 15 seconds or 1 minutes, wow...) Perhaps it is a cross billing issue between providers?
I HATE that stupid message. It will be the second reason I can't wait to dump Verizon Wireless this fall when my contract expires. Yes I have the "You may press * to bypass this message" at the start of my greeting (yes, it is * for Verizon) but nobody else does this so it is always an insulting guessing game. But just like we sheep consumer blithely accept more and more advertising shoved down our throats so goes the message. I can't wait for the day when I get the verbal instructions on how to use the numeric keypad, (You may now leave a numeric message. To leave a 1, press the 1 key, etc.)
Gosh, helpful Verizon... Maybe society is really becoming so mentally limited this type of stuff is needed.
