Bad bad service from DStv

I have been speaking to DStv since December 2020. I am trying to reset my password. They were supposed to phone me back but I am still waiting. 7 days ago I logged a complaint again. Been speaking to 3 agents with reference number: #INC-336427. I keep on asking to speak to a manager and they keep on telling me it is all resolved and an agent will come back to me. It is still not resolved and the more I ask to speak to a manager, the more they tell me an agent will come back to me. Why will the managers at DStv not get involved to sort out this mess. I want a manager to phone me and sort out my problem so I can log into DStv.
