How can I cancel my "free" trial period of acaix3 before I get billed?

This company is a fraud.  There is no phone number because they use call center to take orders and they are the only people  you can get in touch with.  I got an adress from the call center to send a letter but guess what?, the  address that they gave me doesn't receive mail.  I think were out of luck.  The only thing to do is do everything you can to destroy their reputation.  File as many complaint as possibe.  Get the word out to everyone.  Maybe even call investigative Television.  That is the best advice I can give you.

your question is old, but here is the answer....you probably cannot successfully cancel.  i tried.  i phoned the number originally given upon order, addtional orders were still sent and billed.   i actually tracked down an email address and requested cancellation....didn't happen, still got more and billed. I called my credit card customer service line to find out how to contest....they helped.  i completed a statement explaining what i'd try to do to stop the order; they did not require me to pay that charge, and they recommended i convert my credit card to a new number so that future billings wouldn't go thru.  sounds like this has happened to a lot of people, because they knew exactly how to help me.
