Lack of response from COJ and charges for services not consumed

I have been living in my house for 6 years now. I have a prepaid electricity meter with City Power. I buy electricity every month. On 6 October 2025 I received my statement from COJ and it had a charge of R1240 for electricity, I wrote an email to COJ the following day on (07 October 2025) to enquire about the electricity charge as I didn't know what it was for since i use an electricity prepaid meter. Despite numerous follow-ups my email has not been response to and today 27 November I am getting a termination of services. I have been paying my rates except for the electricity charge since I am still waiting for clarity to understand what that is for. I am desperate, their phones ring unanswered, emails are not response to. Can i kindly get some intervention. My account number is ***
