Escom *****ing consumers money

in August 2020 eskom changed our 3 phase meters with a single electronic meter. the reading on the electronic meter was 5 units . my account is up to date . i took the readings every month ( with photos of the unit ) , phoned in the reading and paid the account . eskom still billed me on the 3 meter system . i paid the account as presented to me to keep up to date. in january eskom suddenly took the total reading on the electronioc unit as from date of installation and billed me for all units used . so i have paid double for the electricity i mailed all proof of readings and payments during this time to a certain THABISO MOKEBE in the complaints department he simply refuses to assist me with yhe complaint . He also delete my e-mails without reading as my report shows . i believe that eskom is *****ing a lot of money from customers and there is absolutely no one to assist us. I believe Eskom is a huge culprit in *****ing money from consumers . is there any way that we can fight them
