Subscriptions added on my account without my appro

i received my jet statement for the month of September and it shows that i subscript for SMS air subscription and Mobile content fee, i have no idea what this is for and i am not prepared to pay for it because i already have a cellphone contract so it does not make sense for me to want to subscribe to this, every time i call i am put on hold for more than 10 minutes of which i feel its unfair because now not only am i going to pay for the call its totally unfair and this is such an inconvenience on my side, i requested them to correct the statement and i was placed on hold again
