Eskom account quiry

I am a customer who pays the electric bill all the time. June 20201 after my eyesight was affected by being sick, I gave an incorrect Eskom Meter reading, the reading I gave was 74241 instead of 71241 for one of our 3 meters. The account invoice was received on 29 June 2021 and the amount due was R11 432.79. I called Eskom and made them aware of the error in meter reading which resulted in the account being so high( Ref no for the call 43843****) and was told to pay the minimum that i pay monthly, then call to and submit correct reading on the 12 July 2021, which I did. Later on 12 July 2021 I received an email from Lindiswa Thafeni from Eskom requesting that I email the photos of the meter reading because the one meter is the same for June. I emailed the photos on 17 July 2021. I received the account invoice on 20 July 2021 which showed that the meter readings were not corrected and it was estimated reading not actual reading with the amount of R9 778.38 due. I called the Eskom call center again on the 28th July 2021( Ref no for the call 44516****) and was informed to send the photo of the meter to customer care which I did. I received an email on the 3rd Aug 2021 stating that I should send an email with all 3 meters for a rebill to be done. I sent the requested email with photos. On the 10th Aug 2021 i called Eskom call center again to follow up on the matter and was told that they are still busy with my request. On the 14th August 2021 i received the account invoice which states that an estimate reading was done and the amount due is R11 590.66. I need assistance in correcting this matter as Eskom is failing to assist me.
