Call their toll-free number (1-866... or 1-888... or 1-800...) from a PUBLIC PHONE booth.
Why? Because everytime they take such a call, they have to pay at least $0.50 to the phone company of the public phone booth!
Please do the same, because this is what you get out of it: they pay you to hear your complaints! The more you call, the more they have to pay!
The number they gave me was 1-888-336-3169 - and I called this number today at least 20-30 times... That costs them at least $10 to $15 - and probably much more, because the $0.50 that these scammers have to pay for each call is the minimum amount. It can be as high as $0.75 per call.
