Worst metering system and over billing me for nothing

In September 2021 I moved to Woodwind Estate. My electricity bill was about R400. By December 2021 I was paying R700. In March 2022, my bill escalated to R1200. When I complained I was told that I was being charged a sewage rate of R283 plus water. Which was not communicated to me before hand. I have been going back and forth with Metershack regarding over-billing me. I even logged a complaint with NERSA. I live only with daughter (7) and have never had to pay so much for electricity only. Raudev is charging us R269 for sewage and water which means my bill with Metershack was supposed to have decreased. Instead each time, each month my bill keeps increasing. I’m currently paying over R1200pm for electricity alone. I’m unemployed and always use my gas stove to save electricity, but nothing decreases. Even during load-shedding my meter still runs. You will never see R0 on my statement. I have become a target of abuse by The Metershack because they believe I executed a petition against them around May 2022. The petition was done by all tenants, not just me. I have asked around about 30 tenants and non of them pay above R700 for Electricity. When I quest The CEO Andre he has told me to my face that I will never find proof that they are overcharging and laughed on my face. Can someone please help me report The Metershack. Suggest any organization that can help.
