I had the same charges two; and was able to find a phone number for them, which is 877 317 0189. I explained to the person that I ordered the Acai Slim and Bromalite, but I never got the product; and also said I didn't think it was a big deal that I was out only $5 shipping and handling for each. But when I got the two $80 charges on my card, that's when it became a big deal.
The person I spoke with said that the terms and conditions are on the site that this sets up for a monthly subscription for each product; and I told her that I didn't see the terms link and wasn't aware of the subscription charges. She canceled my subscriptions for each and agreed to have my account credited for the charges. She provided a cancellation number for each subscription and also a refund confirmation number for each amount that I was charged.
But all in all, it really is a charge that you unknowingly authorized. But many, many of us didn't/don't see the terms link at the very bottom of the page. So when we put our credit card numbers in, this gave them the authorization to charge.
I typically read the terms, but if I don't see it, I think there aren't any consequences. I've learned from my mistake.
