I ordered a free sample and paid the shipping of $4.95 and received the bottle of Acai Berry diet pills. THat was all I ordered and now on 10/26/09 my bank shows a charge of $79.95 for what I do not know. I have received nothing for this charge and did not authorize it. How do I get this straightened out ? I have tried and they say they know nothing about it. Please help me as I live on my Social Security and cannot afford this. Thank you.
