Colonx review: 30 day free trial

responded to a 30 day free trail and agreed to pay for shipping. Received product 10 days after order and was billed 4 days later. Called to dispute and cancel. I was told I would get an e-mail and I could respond. I sent 3 e-mails with no responce and received another bottle of pills. called again to talk to a superviser and was told I could only wait for an e-mail responce. I only authorized the shipping charges to my credit card and nothing else. Since then I have been billed 89.00 twice. I believe this is a scam, you do not get a free trial or the time to use it before you are billed for more product.
