paid my dstv but they disconnected it

Im so frustrated because last week monday (02/02/2015) my fiancee and i paid our dstv account and on thursday (05/02/2015) it was disconnected because they said we didn't pay. i called them on thursday i gave them transaction ID and Reference that we used to pay and they reconnected it .but yesterday morning when we woke up it was disconnected again with the same reason and today we send them proof of payment and they sent me automated email to say the matter we will be resolved in 24 hours. i expected them to switch it on immediately because they are the ones who are not doing their job properly.
