Acai Berry Maxx (FX Supplements) Scammed me into a trial offer then charged my credit card without my authorization Arlington Texas

I accepted a free trial offer for Acai berry Maxx and all it stated was that I would only have to pay $5.95 for Shipping & Handling. After that trial offer, I was sent two more bottles without my ordering it and then a couple of weeks later, I received another two bottles without my ordering them. My credit card was charged twice for $85. I never received an invoice for these supplements, all I received was a pink letter that told me that they were going to keep charging my credit card every 30 days. They stated that if I wanted to cancel this "renewal" program then I should email them at cancel@acaiberrymaxx.com (which I couldn't access).
I called my credit card company and they're investigating this scam and they are issuing me a new credit card.
I'm disappointed in myself for getting duped into this scam. I saw that Acai berry Maxx was acredited by Oprah and Dr. Oz and I accepted their "free trial offer" (remember, nothing is ever free)!
