My parents are pensioners and not fami**** with online apps so Ive been trying to assist them for 3 weeks but I am unable to get through to Eskom. Called this number *** and was number 9 in que. On hold for 2 hours, eventually reached number 1 in the que then they dropped the call before I could speak😡. I called back this time number 6 in the que, on hold for 1hour and 30 mins then I hung up because airtime delpleted. I've emailed 3 different email addresses found online but no response or the email no longer works. This is so frustrating as my parents are without electricity for 5 days & their food has gone off, it's just a huge inconvenience. All they need is to make arrangements to pay arrears and for their electricity to be restored again but it's impossible if there is no way of communicating. Offices in Bellville are closed aswell, they have been their thrice, What is going on with Eskom???
