HCA Power Garcinia Cambogia pay per pound for every pound lost Internet

I get a phone call from HCA Power saying I had been chosen to try their product, and get paid for every pound I lost.  I had been researching the Garcinia Cambogia from the Dr Oz show, so I thought it was legit....Well, after reading all the ripoff reviews I realize I was scammed.  I am very upset they took advantage of my credit card, and also that my credit card company won't stop the payment while it's pending.  I pray I can get this taken care of, along with all you other people being taken advantage of also.
