They send you a trial offer for $3.95 and give you 14 days from the time you place your order to cancel your order. The problem is you have less than 7 days to try the product to determine if there are any benefits to this product. When you call to ask for a return authorization number, no one answer the phone, it keeps playing music. I have tried multiple times to call them at different times of the day, still all I get is the recording. I have also tried their e-mail address for billing as noted in their website, but it comes back as undeliverable.
