1 - 4 hours has been 10 days now

Where do I start? Something so simple as to link an email to an account for DSTV-now has left me waiting on a reply for 10 days now. Explaining the problem 5 times, each to a different agent via the online chat left me with 5 chat references and 5 escalation codes and promises of fast track with problem being resolved within 1-4 hours. Every time I follow up on progress, none of the escalation codes exist. No-one is willing to give me a name or number or email address so I can speak to someone regarding my problem. What to do now? Hopefully this review will have a quicker turnaround time than the channels provided. First contact and promise to resolve the problem within 1-4 hours was on the 24th of April. What can I do more?
