FNB PATHETIC SERVICE CREDIT LISTING ERROR

I have received absolute dismal service and am extremely appalled by the efforts made by FNB to resolve an incorrect Temp Loan, which I have no record of taking, on my credit report since January 2020, which is stating I am erroneously in arrears of. Which is highly unlikely for a Temp Loan. I am a Premier Banking client, and I am disappointed at the service. They also closed my complaint without anything being resolved at all. This has been ongoing for several months, with no definitive outcome and has negatively impacted my credit profile and has hindered us from applying for a bond because of FNB's inadequate service. No one is able to help me at FNB, they continually escalate the issue to someone else.
