I saw theri infomercial, and called the toll free number. I hung up when I started to get an idea of the cost. The big mistake I made was forgetting to input *67 before dialing, to prevent delivery of my phone number to them. Since then, I receive 3 or 4 calls EVERY DAY. Caller ID only identifies the caller as CALIFORNIA. They never leave a message, and if you pick up, there is no one immediately on the line. I've noted 3 different phone numbers: 415-466-2093; 925-524-3993; 323-281-1328. If you do an online search on any of the numbers, you find other people having the same harassing experience.
