Eskom accounts incorrect. No response to queries

I reported a problem with my account 3 times already to KwaZulu.Natal.co.za. I received an account in June/July 2024 of R16 000 which I settled in full. Eskom accounts use the same meter reading for the large accounts from 2024 to send me new accounts and my account is just getting bigger and bigger. No response to my letters or queries. Just threats of switching off the electricity. Reported this on the app as well Reference ***, reference ***, and reference ***
