Payment wrongly allocated

I keep getting a message that my payment has declined and im being charged extra amounts on my payment I have two orders.

One was placed on the 20/04/2025 at Makro Strubensvally for R3080.30 and 3 equal installments of 1026.78. I paid first installment with purchase. 2nd one was paid in may. Last payment was paid in June as per African bank statement attached but I keep getting notifications that payment declined and i see the payment keeps going up.

Second order was done on the 13/06/2025. I paid first installment with the order and second installment was paid on the 25/06/25. Last payment is suppose to be due on the 20th of July. However this order shows as fully paid and the previous order which is supposed to be full paid shows as if its not paid.

Please rectify this and reverse all charges on my account

I chat with Yinela she said she escalated and never came back. I sent email got a reference *** but no feedback. I tried calling it says your agent can't take calls
