DSTV Catchup not responding

I have a DSTV Explora which I pay for every month but I feel that it is not worth the expensive premiums. The catch up channel is not as responsive as it used to be? shows that are supposed to be available on catch up an hour after they have played only appear on catch up a week later? I have tried switching the power on and off and removing the smart card but with no avail. I'm really not impressed with DSTV services and might as well terminate my subscription. I am hoping that someone will get back to me and assist with a solution.
