Credit Bureau Update and Account Closure Confirmation

Good day, I had a FNB personal Loan which had been paid off in December 2017. After checking my credit profile I noticed that this account was not updated with the Credit Bureaus and show outstanding balances. I logged a query with FNB (Ref ********** Q) and received the below response:

Thank you for your email.

Kindly note that your loan was settled and your account will be closed off within 45 business days. Thereafter, a final paid up letter will be sent to you.

Further note, a request will be sent to the Credit Bureau for your Credit Profile to be updated, the turnaround time is 7 business days.

This account was settled over 14 months ago. This response is unsatisfactory and require the Should I have not queried this I would never receive the closure and Credit Bureau would never be updated. For 14 months nothing has been done, why do I now have to wait 45 business days for this to be sorted? I want this account closed and all relevant documentation and updates completed ASAP!!!
