Complaint against FNB CALL CENTRE

Today (2025-03-03) I visited Potchefstroom FNB brach at about 13:05 on my lunch time regarding my debit order date on my personal loan with the bank that I needed to change with CALL CENTRE as discussed last week Friday. I was correctly assisted as the branch were they called their CALL CENTRE as they are the ones directly dealing with issues like this and not the branch. I hold on the phone for an +/_ an hour. I tried calling the CALL CENTRE four(4) times with no luck. It's either the phone is answered then dropped, the phone just cuts off after a long hold or the phone takes you straight to rating service. How can I rate someone before I can be assisted? I even ask one of their employer to assist me and he also failed as he was also getting the same experience. I feel I waisted my time and petrol by going to the branch. The service i received from their CALL CENTRE is very very poor and frustrating. If this this how we clients are treated because I feel it's deliberate, their conduct is unprofessional and it can't be tolerated.
