Lazy and not willing to help

I have called the help line to explain that my cell phone was ****** and that I need to change the contact details so that I can load the app on a new number , The agent "assisting" me recommended I do it online without any offer to assist or alternatively go to the branch . So I tried online to register for online banking but it said I should go to a branch (clearwater mall) where they were less than helpful they took me to one of the online banking PC's . I entered my details and should them the error , they advised that I need to activate online banking at ATM but I told them I don't remember username or password as my phone uses finger print sign in. They then took me back to a PC where I entered my ID, Card number and Pin but system says ID is incorrect at which point I was told I need to call the contact centre , I wasted over 3 hours trying to fix something standard bank was able to do in 20mins . I am very unhappy and I am seriously considering closing this account.
