Fixing admin

I am a student and I have the student account with ABSA and this year I’ve been charged as a graduate even though I’m still a student. I went into my branch two times already to submit my proof of registration. Both times the person who helped me did not know the email address to which it has to be sent to. Upon searching for it they finally sent the email and said it will be fixed. It’s September and it is still not fixed. I do not enjoy having to go into the bank to speak with people to fix the problems( especially not twice), let me submit it via the app or a similar approach, since there is somehow a communication gap between the bank branches and the people behind controlling accounts.
