Telkom Debit order rejected *****

I received a bill in April 2026 with an additional charge of R202 which I was unsure about and made my normal payment of R599.00. My account has never been in arrears but in May R2026 my account was suspended because I didn't pay the amount of R202. This is apparently due to the fact that the debit order was rejected. I am no longer using that account and Telkom is the only creditor debiting my account. As per my understanding using debi check allows debit orders to be made only when there is money in the account. Telkom app states my debit order is due on the 5th of each month, I told them to have the debit on the 1st of each month and I see latest debi check date is 25th of each month. Telkom debits my account whenever suits them and now I have to pay rejection charges which is unfair. They also don't want to open my line until the R202 has been which is bullying. The consultant also told me that the rejection fees will be billed on my May and June statements which is not right. Please can this be removed and my account re-activated.
