City power

I am writing to complain about City Power. Despite our City Power connection being disconnected on 12 May 2026, we continue to receive unjust postpaid electricity bills. Since September 2025, we have been incorrectly charged postpaid rates while simultaneously purchasing prepaid electricity. We raised this issue with City Power and provided proof of our last six months of prepaid purchases. The response we received was that our consumption was too low, and the billing would continue until June 2026. We explained that we have a solar system at home, which reduces our need to purchase large amounts of electricity. Following this, a City Power contractor audited our meter. A week later, we were wrongly accused of tampering with the meter and threatened with a fine, which we refused to accept. Subsequently, our meter was disconnected, and we have been completely off-grid, relying solely on our solar system. Despite this, we are still being billed for postpaid electricity. This month we received a billing of over R125k. Can someone please help with this madness.
