Buckmasters Started a membership with out my permission Montgomery Alabama

I was contacted on the telephone by buckmasters offering a membership to their program. I was then asked for a credit card number. I told them to send me some info and I would decide if I wanted to join. I did give them my address. They then proceeded to send me a bill for the membership. I called telling them  I did not sign anything and did not want to be a member of their organization because of their forcefull techniques. They told me that basically it was too bad and that they had a recording that indicated I told them I agreed to join.

They now call telling me that they are sending me to collection.
