Eskom delay or failure has caused serious sickness to my grandmother-Ref ***

I am not happy with Eskom based in Marburg-Port Shepstone. I reported a matter long time ago. My grandmother is old and sick but Eskom failed to meet her needs until today. This reference '***' will reflect how many times I have logged an issue with them without any help/customer satisfaction. Meter Number is ***, which they claim it is not registered. Here are my grandmother's details: Mavis Dlamini-ID No: ***. Contact No: is ***/ ***. The problem is when Eskom is going to the area they do not call an hour or 30 minutes before they arrive, they call when they at the property_ that is not acceptable. We are busy during the day and becomes difficult to organize someone to open the house for them. They need to be organized and plan their work. Their turnaround strategy is madness because they can not keep up with it. They say customer must wait approx 8 hours but days past without them arriving. We need to have eletricity by end of business today. We are willing to play our part but what about ESKOM??? We are not served well. Can this matter be escalated to Manager's office perhaps their intervention will make a difference. Another issue is Eskom no longer allow walks in, now we must via the call centre to report an obvious issue,even worse Marburg Eskom is close to where my grandmother lives. Please act now!!!
