I signed up for a free trial of Colon Cleanse and paid the shipping by Visa. I have been informed by my bank that a charge to my Visa will be forthcoming within the nest couple days. I did not SUBSCRIBE to this product. I have no way of getting in touch with this company to remove my name from their mailing list. I have not tried the product as it was just received but after finding out about them I definitely do not want to subscribe. How long does this go on?
