We ordered the trial offer of the Acai Berry Detox. We decided that we did not want any more of the Product so we told them not to send anymore but to cancel any more orders and not to charge our credit card with any more charges. We even wrote them a letter to this affect. They said the order was cancelled. But we just got our bank statement for this month and Feb. and there is a charge on it. What do we have to do to convince them that we do not want their product and do not put any more charges on our card? The product doesn't work any way.
