After receiving the sample I realized I couldnt use it and also found out I needed to opt out of some kind of membership so I called and told them I would not authorize any further payments or enrollment, yet I was double billed this month (September 2009) for $79 each. I tried to call and cancel again but the number the payments are going to is disconnected. I never received anything for that $160 either! How can I make them give the money back? How do I get a hold of them.
