FNB Debt Review unnecessary waiting times for simple processes

I have a paid-up account number *** which was settled through your debt review department, I need a paid up letter so this process can be closed and finalized. You contact centre agents are telling me it takes 3 days to get a paid up letter. How can this be? The account is fully settled and payment has been allocated. 3 working days for a paid up letter is just ****. Other banks this is an automated process, as soon as an account is settled in full, paid-up letter are immediately auto generated. For a bank of your size I would expect nothing less, clearly I am wrong. I need this letter ASAP, I can't wait 3 working days, for what? Up your game please
