No assistance towards customer

I have changed my personal details within the Three Rivers branch, very helpful but when I got home to go on my internet banking all my old details was still there. I phoned the customer call center to tell me what they did but the security questions was not relevant to me at all and the manager was not helpful at all. I just got told that I must go in to the branch to sort it out or phone the next day. My question is must my whole business now come to a stand still because Standard Bank has no idea how to help their customers. They are putting my business in jeopardy and there for I am forced to move all my capital to another bank that can help customers.
