Telkom is try to rob me out of my hard earned money

Good day Telkom is trying to ****** money from me, may I kindly get assistance regarding the issue. I had two accounts with telkom until I decided to have the canceled, so month end of August 2024 both of their debit orders were unable to debit from my account and when I realized that I immediately phoned telkom call center they told me that I need to make the payment to avoid suspension, but then I decided to rather have both accounts canceled and the consultant that was helping me on that day told me the amounts that I need to pay on both accounts and she further told me that I need to make those payments before the end of September 2024, the consultant was so rude she even refused to give me the banking details and hanged up the phone on me. On the 20th of September I phoned the telkom call center again to request the banking details and the reference numbers to use on both accounts and I discovered that a penalty fee of R200. 00 has been added on both accounts, the consultant told me that it's for the debit order rejection for August 2024,i comp**** since I was aware of that and on the same day I paid the settlement amount of R2587. 70 on one of the accounts. On the 27th September 2024 I paid R307. 70 on the second account as instructed by telkom. The following week I phoned telkom customer care to request the paid up letters on both accounts but the consultant informed me that they have received the money and it does reflect on their side however they are just waiting for the account department to update it on the system. Month end September and month end October they tried to debit my account but they were unsuccessful and now they want to say I owe them R400 on each account for the debit order that returned unpaid and my quirie is that why did they try to debit my account whereas both accounts were fully paid up before month end September, why try to debit for a paid up account? I have proof of payment for both accounts and the emails where they confirm the amounts that I have to pay for the account to be settled.
