never got a trial as promised, just the "whole enchilada" Unable to contact. Have refused shipments and still keep sending (and charging) me for product I don't want

I ordered the 14-day trial of Pure Acai Slim, order number 4140054, and the advertisement website said only pay shipping of $4.99, but I was charged $79.00 instead. I emailed the company many times to cancel my order before it was shipped and they did not cancel it. I want a refund because I am in my 14-day trial period as the refunds and exchange policy states. Please refund the money back to my account, order number4140054, and cancelany further shipments of your product to my address.
