Pathetic customer service

I went to the shop on the 26/9/2020, to buy some few items and then pay extra to my personal loan account. I bought my items for cash and then requested to pay my loan account. I paid for my store account on the 25/09/2020, and was not going to pay for the same account on the 26/09/2020. The cashier , who looked not interested, when i think about it now, actually, paid the wrong account, which is the store account. I only realised on Monday, when, i checked balances that, she actually, credited the wrong account. Can you please teach your cashiers to be attentive to your customers. The cashier was Nontsikelelo Mdluli, at West street branch, in Durban. My identity number is *** GN Nkosi. I know you cannot anything about now, but it is sickening , to be serviced by someone who does not listen to your request.
