Fnb a dissapointment

My retirement annuity with FNB debit order for June has not gone off for some reason. So I been quering from the 1st,spent my airtime on the call Centre with no resolution. Went to the bank personally to spend hours on their phone with the call Centre. They reassured me it will go off on the 3rd.it hasn't gone off. What's frustrates me, I have chosen this bank, that I'm loyal with for 10 years that can't seem to help me. All I'm asking that my debit goes off so my retirement doesn't get affected, I'm not asking for anything else. Although the request seems simple it's becoming so frustrating that I feel that I'm taking myself to another bank. I don't want to speak to another consultant, that frustrates me more. We meed to do better. I'm frustrated and angry because you are dealing with my future. If you can't help tell me, so I can switch to a bank that can.
