Pimsleur Language Learning Systems Pimsleur Approach Unwanted Products, Unauthorized Debits Internet

I ordered the Learn Spanish CD for $9.99.  Without my authorization or consent, the company signed me up for Gold Courses 1, 2, 3 and 4.  They have been debiting my bank account for $64.00 each month, and it will not end until they have gotten $1,024.00 for all four of these courses.  I can't close my bank account or prevent the debits without causing more problems.  There is no physical address for returning the unwanted product, nor does the company provide an account number for making sure that the return is credited.  The phone number (866) 774-4754 leads to an unpleasant individual who rather than resolving the problem or accepting the cancellation simply hangs up on you.  There are laws out there to protect consumers who take free offers from being signed up for, and charged for, expensive products they never ordered.  I suppose that Pimsleur Approach gets around this law by charging for the initial purchase, so it's not a free offer.  Still it is totally outrageous to charge people for products they never ordered or authorized: legitimate online merchants don't do this.  If I order from Zappos or Amazon, I don't get sent expensive stuff I never asked for, and I can return the product or cancel the order without getting charged.  Here I've lost over a thousand dollars on products I never ordered, didn't want and can't return.
