AcaiBerry Power 500 Myeztrim Unauthorized charge of $89.31 on my credit card Davie, Florida

I ordered a trial Acaiberry pills for $1.00 which was charges on my credit card. After two weeks they charges me on the same card $89.31. I called the number that was on the credit statement and asked why they charged for some thing that I don't have knowledge of what so ever. The lady on the phone asked for my adrresse and said will ship it to me. I said I didn't order I don't want it either. She said she is sorry but will not refund the money. My concern is that they have my credit card number and may charge for some thing else too.
