FNB purposefully *****ing up without reason

If I could give it a negative rating I would I had a revolving facility with FNB in 2018 in which I settled and closed in 2020 and another which I settled and closed in around September 2021, they have not updated this information with the credit Bureaus, This has been negatively affecting my affordability thus not having access to credit even with the very same FNB I have since not been able to acquire an asset I desperately needed for my business especially this festive season. I have been up and down with FNB to clear this but they legit could care less, I have exhausted all options
