I cannot pay for your mistake any longer - REFUND ME PLEASE!!!

I have received extremely high electricity charges for the months of July and August 2021. Having requested for this issue to be investigated, it was finally confirmed that there was a fault with the Body Corporates electricity meter which would be replaced and I will be credited for the electricity not utilized (after the charges were reconciled). After various follow-ups, it was further confirmed that the reconciliation would be done before the levy statements for December 2021 were sent out. Having received my levy statement, I was shocked to see that not only was I not credited for the electricity but I also received an electricity charge of R4 686.23 - AGAIN THIS IS NOT AN ACCURATE REFLECTION OF THE UNITS OF ELECTRICITY USED. Knowing that there was a problem with my meter, why is it that AIV continues to bill and debit my account for charges that are not due by me?? Why have I not received a refund to date, seeing that this issue was initially escalated to AIV on 27 August 2021?? Why has AIV not acknowledged receipt of my email today and apologized for this financial burden?? When will this matter be resolved?? Can I please get feedback??
