Trilegiant - Shoppers Advantage - Columbia House ripoff, sent a check, cashed check and it entered me as a member Trumbull Connecticut

I received what appeard to be a check for a refund from Columbia House. I cashed the check because they had recently not been able to send me a CD. I received Shoppersadvantage membership information and when I called they were rude and said it was apparent on the check that I cashed that I would become a member. If I had not cancelled in a timely fashion, I'm sure they would have charged a large amount. Nowhere on the membership information I received in the mail was there a price for the membership. Luckily it was detailed on the back of the letter I received how to cancel this membership without further charges.
