Hoodia Stack offers a free sample of what they call a diet supplement. They only ask that you pay for S&H. I did that, received the product, it contained no return address, no re-order form, no information regarding the product. I immediately knew I had been scammed. I looked online and found this site, many others have been taken advantage of and scammed as well. I called the number on my credit card and spoke with a horrible lady who said I had agreed to the terms and conditions of this product, which I don't remember doing. I never signed/printed any info nor did they ship me anything other than a green bottle of pills. I have been taken advantage of because the S&H charge posted on 10/17 and today is 10/29, yet they said they have already charged me another 60 $ and more pills I did not sign or ask for. I will not accept the package and hopefully there will be a return to sender listed on the product or I'm taking it to the police department to locate/return to sender. DO NOT ORDER FROM THIS COMPANY. I LEARNED THE HARD WAY AND HAVE BEEN TAKEN ADVANTAGE OF. I HAVE CONTACTED MY CREDIT CARD COMPANY AND THE POLICE. ONCE I RECEIVE THE PACKAGE, I'M NOT OPENING IT AND WILL HAVE THEM RESEARCH FURTHER. IF YOU NEED A DIET SUPPLEMENT, GO TO GNC OR ASK YOUR DOCTOR.
