I tried them for a promotional trial period. They bill you quarterly I emailed them to cancel over a year ago as I wasn't getting any leads from it. They continued to bill be but never emailed me to tell me a email or call didn't constitute a cancellation. If you can start a contract via email, you should be able to cancel it the same way. STAY AWAY, ITS A SCAM! Tried to cancel via their fax number which isn't a working number!
