Rooter faulty

I have a VERY BAD experience with Multichoice in that my rooter doesn't have coverage and I reported it and Spoke to Anele who confirmed that it's faulty from their side.A week later it's nots resolved .I was then told to go to a working outlet somewhere in Steve Biko street which I went and that store have moved and the system is Not updated which also cost me money .I called a call centre again daily and spoke to different agents who kept telling they will escalate it and I'll get a call within 24hours which NEVER HAPPENED.I spoke to Batha ile who gave me this ref no ***-i138 .Then I called after 36hours AZOLA said she will escalate and also confirmed that Bongiwe will call me which NEVER happened .I then called and spoke to Elihle who said the same story Wich never happened .Today it's been 5days since I was told I'll be called ,I then called again and spoke to Zimkhita who told me one more time about escalation.Its been a costly three weeks that my issue hasn't been resolved .The sad part is that they keep sending people to stores or outlets that do not exist costing us money .To this point the issue with my rooter is still not resolved
