Zero Service linking Showmax to Dstv account error

Not even sure how to start this complaint and if it even will be read. I have tried assisting my folks getting there Showmax linked to there Dstv premium account. It has now been more then 3-4months where they said the call would escalated and that they would get back to them but nothing. This happened on 4 different calls as there is an error linking Showmax. Showmax said problem is at Dstv. We have basically given up and we have excepted the terrible service. If I go on the indication of Hallopeter then I doubt if we would ever sort this problem.
