Fnb gave me Bad service and listed a paid up account as default

I was under debt Review, on 20 July 2020 I received a clearence certificate. On 21 July 2020 debt counselor forwarded the clearence certificate to credit bureaus for them to update my profile(on 25 August 2020 I followed up with credit bureaus who confirmed that my credit report is updated). Fnb have listed the account which is cleared via debt review as 8months in default. On 24 August 2020 I app**** for a loan via fnb app and was declined. I phoned Fnb customer service number and was sent from pillar to post, I even phoned their debt review department, was adviced to take my clearence certificate to their Branch for ammendment of my profile, on 16 September 2020 I took my clearence certificate to their Branch. On 22September 2020 I followed up with call centre and was referred to portfolio mamager who never answered my 3 calls(the answering machine said I should leave a message, I will be phoned back no one phoned me) on 23 September 2020 I phoned again and was told that I am high risk because of the listed account on default(I explained that the account was cleared via debt review and is updated as paidup on the credit bureaus) I was reffered to risk department where no one answered the calls again the answering machine said I should leave a message, I will be contacted shortly no one phoned me. Sad part is my account on which my salary is deposited with fnb is almost 3years. Im really disappointed with Fnb.
