Customer service

I have savings account with FNB everytime when I want to transfer money it's not allowing me it says to contact call centre,when I do that still no assistant I don't know how much I have spend calling,they transfer me to another department same that department no help they transfer me it's been 30 Min trying to get assistant no luck. What is the point of having a cheque account paying so much when you don't get help.Im not happy with their service at all rather take my account to another bank.How can we help should change to how can we frustrate you
