Some where along the line you put a back up order of $200.00 and since you didn't order. They sent you your back up order...which is in the presentation and the contract.
Call them, download the cancellation form, fill it out and CANCEL. It doesn't take 3 months to cancel the membership. If you have a balance they will hold it against you forever...(like any other store) and if you ever try to sign up again, you will be held responsible for your back balance.
They don't chase you for the money like the rest of the stores will. They just file it and wait.
