Inconsiderate, disregarding FNB

I am unimpressed with the service I am currently receiving from FNB. Unauthorized debit orders were being processed from my cheque account. I approached FNB and I was advised to open a new account, which I did.All authorised debit orders were supposedly moved to the new account.I was shocked when 3 months later I started receiving calls that my revolving loan is in serious arrears.I was shocked because the loan is auto payed via transfer and linked and can never go unpayed for any installment.I approached FNB and it was discovered that the loan payment authorising from that I had completed,was NEVER captured although I had sent it way in advance.I am frustrated that I am constantly recovery collection phone calls from different Collections Agencies over something which is not my fault. FNB is failing to help me or come with a solution to stop this harassment. I subsiquently made an appointment with the Middelburg, Mpumalanga branch Manager of FNB for the 16th November 2022. Upon my arrival at the branch on our appointment date and time,I was told that the Branch Manager is off sick and there is NO-ONE who can assist me or listen to my ordeal. I was turned back and promised that I will receive a new appointment But to date I have received no correspondence from FNB. What pains me even more is that I was never informed that the Branch Manager is not at work and I took leave from work only to be turned away like a fool.
