horribly daft bank

If I could give zero I would I had a minimum payment of 3040 rands due 1/4/26 which I had paid on 11/3/26 above that: 3075 rands . It shows 0 rands due on my app. What does discovery do? contact me endlessly for zero rands , and restrict my account, and they have sent me messages and emails before for zero rands. I am very busy and can't sit on the phone so I used the whatsapp customer servise, showed what my app says, the POP showing I paid and I spoke to Siyabonga who was more concerned that I should know she is a female banker via whatsapp (with her gender neutral name ) she then said I still owe this amount as if she ignored my POP and ended the chat .
