Fee reversal

Good day I have been a loyal Telkom customer for over the past three years and since I started using Telkom I’ve never had a problem with paying my bill and for over two years I’ve always been a cash payer I will transfer every month on the 25th and have never had any issues but in August 2022 I did a transfer on the 25th but to my surprise on the 31st they debited my account and since I’ve been in good standing I reversed that money when I received my statement I noticed that put a charge for not honouring a debit a charge of R202 and interest of R23,50. I called in to query this and I spoke to a very arrogant gentleman who refused to assist me and he refused to also send through my request to escalate or to someone in a senior position so I’m left with no choice but to query it here I want to have those fees waived as I have always been a cash payer for over two years so where is this charge coming from please correct this as soon as possible.
