Eskom - Impossible to submit meter readings

I usually submit my metre reading on a monthly basis using either "My Eskom Customer" App or online however over the last three months it is impossible to login to the App or online. A constant message: "A Technical error occured. Please try again later" appears on the App and its not even possible to log in online. Try calling the customer line and once you have selected the region a voice message informs you that they are busy. So in a nutshell, as a customer, you cannot submit accurate readings to avoid ********** billing, nor can you talk to a customer service agaent as that is blocked as well. All in all absolutely no customer service and certainly no facility to solve any problems. I also sent an emial and received a reply telly me that I had not filled in the subject kline correctly! REALLY?????
