Winners Readers Service Billed for accounts not opened, Phoenix Arizona

I have been round and round with these people.  They first called and offered a package of magazines that appeared to be a pretty good deal but turned out to be way more expensive than individual subscriptions.  After their account was paid off they offered bonus time etc.  I told them I did not want anymore time and please cancel.  I called because they sent me a late notice and insisted that I signed up with them for magazines again and one of the magazines on the list I have never received.  They insist that the magazines cannot be cancelled and I have 14 more months to pay.  I asked for paperwork for changing the magazines and received it but it says I have zero issues and zero years left and to change a mag I need a full year left.  A return call got me an answering machine that advises me that I will get a callback within 24 hours.  I am not holding my breath on that one.
