BILLED FOR CONTENT THAT I DIDNT CONSENT TO!!!!

I do not look at my statements as I know jet only bills me for the interest and the item I purchased, today I look at it and I find that I am billed twice a month for services I do not even have and did not even consent to having. The one is SMS AIR SUBSCRIPTION and the other is MOBILE CONTENT FEE, I call Jet and they say I have to call some company called RMCS, apparently that is they mobile company which handles all their mobile related services. my problem is why does this company have access to bill me for content I do not have or did not approve to having. Utterly disappointed with JET!! I then call this company RMCS the consultant doesn't know herself what these subscriptions are and keeps saying another consultant will call back and explain it, how do they employ people that don't know what they are selling. Secondly she said that I consented via sms to get approved for these services which I did not.
