Worst bank

This is the final straw for me, first thing Monday morning I am moving over to another bank. They somehow linked my account to my father's profile and gave my father signing powers over my account! This is my own account which I opened about 11 years ago. My previous account with standard bank was when I was still a minor but that account was closed and i opened my own account when I started working. My father has now received notifications of my spending and my Account balance as sms's. This is absolutely shocking and no one can assist me as this is a technical error. Was told my father must go into a branch to resolve the matter. Why? My father did not go into the branch in the first place when standard bank decided to give my father signing powers over my account ad well as send him a message to show him my bank balance! That is against the popi act as my personal information was sent to a third party.
