I have got the same problem with this so called "company". I have tried to cancel my product, but could not do it because they have no real website for "login" (they provided it but never works), and when use their auto phone system to cancel, the message is that they can not find my record.
What heck! They charge my credit card every two months! I really don't know how to deal with them. Want some advices from people who have encounter the same problems.
Hydrodem product does have problems, if it's really good product, the company don't have to do this way.
