Wrongly charged account

I received one (1) bottle of Acai which I didn't order.  They charged my account $89.13 for the month of November and December for a total of $180.93.  I only received one (1) bottle for the month of December, which ia a moot point because I did't order this product to begin with.  I have been trying to get in touch with them to no avail. I will call both my charge account and my lawyer to get this stopped.  It's quite an ordeal, but I had to do this a couple years ago for the same product.  This is a scam from way back.
