Long standing technical problem

<p>I have been calling and writing emails to Multichoice abt DSTV Catchup and the problem with its sound with not even an a knowledgement that my communication was received. I cannot watch anything on catchup because of the sound problem. I pay so much money every month and to have this kind of service is outrageous and frustrating because there is nothing else to do. Do they even check the sound or notice these problems?</p>
