Explora catchup skipping episodes

DSTV is on a drive to win the market by making promises that the explora does not keep.In there adverts,there value prop is based on the user not missing an episode,because you can always catchup at your leisure.It has become a common occurrence that everytime I need to catchup on ISIBAYA and THE ROAD, some episodes are missiing or not loaded. When I call the customer service, I am given a Technical answer, saying there is an issue with my DISH and SIGNAL. Why is it that only the few shows are affected by the signal, this I fail to understand,Surely if this has anything to do with my DISH, all the programs are supposed to be affected.Can someone please assist with a proper explanation and not this dismissive and lazy way of handling issues.I hope I can get a genuine and true cause of the issue.
