NO RESPONSE AT CALL CENTRE - PATHETIC

Our circuit exploded this morning. I have spent the WHOLE day on the phone trying to log a complaint - altogether 2 hours of airtime. No answer at the Eskom call centre. I have sent numerous sms messages. I have sent mails. I can’t register on the app or the self-service option. SO WHAT ELSE CAN I DO. NO ANSWER OR SERVICE FROM ANYONE
