Telkom Openserve

My internet line with Telkom stopped working on the night of the 18 and I called to log a fault, it is now 3 days later and I have spoken to 8 different call center agents and still nothing has been resolved. The one agent told me the technicians(openserve) will come when they ready. No one is getting back to me with any updates or communication and I just found an openserve agent at the house next door to me responding to a customer yet I am still waiting for my issue to be resolved. How do I get any accountability here?
