Faulty updated app made my problem

When FNB updated their app over the past weekend, I got kicked out from my app and online profile. I have raised this issue with my "private banker" who is supposed to help me but she is not doing anything about my problems. I was rather referred to some robocaller that is just as useless. Why am i even paying these crazy fees - for nothing. I don't have access to any online profile currently and no one bother to help me. I logged a call online, but still nothing from FNB. This is really pathetic!
