Question for Multi Choice Nigeria DSTV

I came back from my field work knowing fully that my subscription has expired. I went to renew my subscription and I was asked to pay almost N1,000.00 for over due. Please I need clarification on this because once subscription in due, I won't be able to view the channels. so what am I paying for? I am still nursing the pain of subscription increment coupled with buying fuel to watch DSTV everyday. My DSTV Card number is : ********.
