NOT UPDATING SYSTEMS

I Have a huge problem with FNB at the moment and forgive me if I am a pain, I have asked who I must send paid up letters to, I was told that I should use the *** email, your systems are still not updated, according to Experian, their systems are updated, Why is it that old accounts are still on your systems?????

The email was sent to on the 22/10/2020, how long can it take to update systems???

Also my Covid19 extension plan query was still not resolved!
