poor dont care customer service

My Dstv viewing is totaly switched off from headoffice for the whole weekend from friday night .When i want to correct the error through a phone call headoffice told me i have tu make a payment for using my previous package but i have switched to another package on my normally paydate .My branch where i make my payment never switched my package but took my payment for the new package .Now I have to wait the whole weekend for a investigation from their side causing me a lot of inconvenience because my whole T.V.is switched off although i have made my payment on my due date 19.01 2018 .Which is so unfair .The customer is only responsible for payment on time and ask for switching but Ìs to suffer now for a mistake of the cashier who did the switching of the channels which is nothing tu do with the customer . I have to provide them now with proof of payments which they can see on the computer which is a waste of time and that over a weekend when the shop is close !
