Temporary Loan Paid Up.

I had a Temporary Loan with the Bank earlier this year, as quick bucks to cover the medical expenses for my father who was sick, unfortunately we needed a quick solution to deal with the matter. i have paid up the account within the duration time even better much quicker than expected. recently i app**** for finance to purchase and there is an issue with the credit regulators that i haven't completed paying the bank temporary loan. Due to issues that i have been experiencing with my personal account that was overdue at times as i didn't keep money in the account avoiding continuous with reversal that end up costing me even more. i decided to close the account thinking this will resolve the issue. but nevertheless it didn't help at all. when i check in history i owe FNB nothing at this point, even more i have forgotten that i did a temporary loan with them. when logging a query they assigned it to the Retail Queries Department where i expected a call within 12 to 24 Hours which didn't happen on Reference Number : ***Q when realizing this was not at their attention i attempted again and got a new *** expected a call but never got one. after getting an advise from those with experience of FNB illiterate customer treatment, i sent an email to the fnb care which Im not sure if its a department. following day i received a call to promise further investigation. The next call i get is for me to pay an outstanding amount of R994 from my temporary loan account that was closed months ago already. the reason behind this outstanding amount is because it bounced when they debited my account. All this months the bank have listed my name, rudely didnt pay attention to detail and process my account closure as i paid it in full but this info was internally with them without my knowledge for so long enough that i had to be on their back to get this news of the amount i owe them as they say. as far as i know i paid up my account and i owe then nothing. The bank must account for dragging my name into the red tagged nonpaying customer, they must account for my credit report that failed me in application that could have gained me progress in what i was intending to do to progress in life. i need them to be held accountable and clear my name, their system is a problem to them and not me as a customer. i need clarity on this and clear reasonable case resolution to this matter. they must account, it has never been my issue to pay them, they have costed me a hardship months that were so unsettling, i need to them to pay me back my time and clear my credit. i dont deserve what they did, i fully did my part and now they trashed my name apart, its disrespectful for a loyal customer to be treated in this manner.
