Worse Reply and Experience Ever

My Wife took a Loan at a ABSA Atm for R2000 December 2017. It was paid close to end Jan 2018 as agreed. This morning as she asked ABSA Kenilworth why it is still reflecting as a loan and showing unpaid they rep**** in Branch at Kenilworth that it is a different department but they can see it was paid. So she asked them to just give her a letter stating it was paid.They refused and said they will follow up and it will reflect in 7 days time as paid then she will receive a paid letter.

All she wanted was a letter to show it was paid
