Exceptionally poor service

I find the service received from S Nkuna (Business Banker) totally unacceptable. S Nkuna is also not picking up her call phone calls. A mail was sent to her on 22 Oct 2025 advising of the new directorship registered. I received a phone call from S Nkuna confirming that the account has been updated and will continue running smoothly. Today I received a letter that I cannot open regarding breach of contract on the loan. Loan is paid to date and I also now realize that my accounts are blocked. Further to many transfers by telephone at FNB, I was told that the directorship was never changed and that the accounts are now in the deceased department. The company and account is still active and this sudden transfer to the deceased department is blocking the company to continue with business and to honor debit orders being presented
