DSTV KEEPS ON TAKING AWAY CHANNELS FROM PACKAGES

I signed a contract with DSTV for the compact package. That is an agreement "I pay x amount, I get the channels on the package". Not long after that they removed History channel that was on the package, I contacted them numerous times, they just ignored me. Then I noticed more channels missing and even yesterday I noticed 2 more channels on the package was removed.

I mean, I signed a contract, I agreed on a package with certain channels, I pay the amount every month. And they just keeps on taking channels away we agreed on.

Is this *******? Just thinking out loud.
