Asked to pay for additional decoder which I am not watching

An additional Compact Dish was added in my name and now they forcing me to pay double the payment which R1004 altogether including service that is not on use by me. I paid for one compact which I have been using for over 12 years now. I have been told to pay for two decorders while I am only using one, or else they wont re-connect me. The call center agent was Zanele Mesate and Nomcebo. The two was really helpless, even after I asked them to investigate who is watching the second dish and where is it being watched.

Now I understand why people are moving over to other service providers like Netflix and etc. DSTV service is really terrible and arrogant.
