Bad client customer service - change of debit order details.

I phoned the Cape Town call centre to change the details of my debit order as I change bank accounts. I tried to do this online, but the online fascility do not have an account verification facility for FNB. After wasting my time for how long, I was told that I have to physically get into my car and drive to the walk in centre to change this. This is outrageous. In today's day and age - really ?! The call centre operator was totally ***********.
