send us messagges that notifies us how much we must pays you,and the reason why 99

I'm very much disappointed in their services no sense of urgency, I woke up my dstv is disconnected, when i call them to find out why because i paid my account before the due date, they say I owe them reconnection fee for the month of September, and my dstv was never disconnected now they say I must pay them R100 for the reconnection fee of September plus the reconnection of these month,and they never notified me that I owe them, it was my suprised when i find out that it is disconnected today
