Eskom email address for account NIGHTMARE

I have tried over a few months all platforms and ultimately every time sent an email to Eskom Western Cape trying my damndest to update my email address as i cant access my old email and therefore can access eskom AND dont receive my monthly BILL !!! I get a polite reply every month and its now month 12 …..they havent updated my email address and I still dont a year or two later receive my account……i am blindly paying an amount but i think it is shocking that you cant call anyone and get looped on a machine and then when email is sent NO response or call or further email is done! come on please !!!!!
