DSTV disappointing service delivery! !

It is my understanding that dstv works on a prepaid basis for the provision of their services, however in January of this year because i did not require the service as i was mostly not available at home i did not pay the subscription but viewing was not disconnected. I subsequently did not utilise my dstv till May at which point i phoned customer service to enquire about how much i needed to pay to restore the service, i was to my surprise informed that i had to pay 2months worth of the subscription plus the reconnection fee. I was puzzled by this because as far as am concerned i did not pay for the service when I did not require it and i shouldn't have to pay for it. I need to be reconnected ASAP without having to deal with poor service delivery. I am thoroughly disappointed.
