POOR CUSTOMER SERVICE

I recently upgraded to the premium package. I initially tried to do it myself on the DSTV NOW APP. This did not work. I called in to speak to an agent, who helped me somewhat. I needed secondary decoders connected through extra view. This has still not happened even after me paying....like a good subscriber. I cant even call the call center back..... all the numbers listed nationally are saying," the number you have dialed doesn't exist". I have called 38 times in the last 12 hours......to no avail. How do I resolve this problem?
