Very poor customer service from Telkom

I currently have a 80gig mobile lte internet data package, 40gig anytime data and 40gig night server data with Telkom mobile. Costing me R199 pm. For a while now I have been struggling with Telkom in a dispute over debit orders going off on my account on the wrong date when salary is not yet in, therefore been penelised on the account. I have settled the account up to date and have requested to pay the account via EFT hence been Telkom debits my bank account on the wrong date which is supposed to be on the 1st of every month, I paid my account every month since the last dispute via EFT on the 26th of each month and every month after I have made payments and released payment immediately Telkom still tries to debit me on this 1st of each month sometimes several times in each month where there is no funds available in the account, and they keep on adding penalties. I have repeatedly requested from telkom that someone in management contacts me to resolve the issue which the fault is not in my side but on Telkom's side, no one has contacted me since request has been made, I have also requested an email address so that I can forward the proof of payment to their accounts department upon immediate payment via eft to Telkom was told that such email can not be provided and is still ignored, I am currently under debt review hence the covid pandemic my salary was cut and changed my bank account and the bank account that Telkom tries to debit me is no longer in use, I have repeatedly told Telkom this the still ignored me and kept on debitting me on that account after each month payment immediately clears to them on the 26th of each month. They have since suspended my account for the past 2 months I have decided to not pay Telkom one cent on the account until someone in management contacts me so that we can come to an solution to this problem. I have not skipped one payment to telkom for the past 2 months
