FNB Customer has to send FNB Statement, So silly

App**** for a credit card last week, got approved as its surely on my app. I called the call centre now who says I need to send bank statements however where was this communicated to me FNB? How can you want 3 months bank statements but I am a FNB customer, doesnt that sound silly? If i didnt call and ask, would no one contact me?
