My accounts are blocked

My account has been closed, I can only login and I cant access my accounts now. It's been months now. They refuse to open my account. So if am not able to go to the branch I won't get help? Because now am at mpumalanga taking care of my sick granny, I won't be able to go to the bank. If they no longer need me why dont they close the account because the app it's just there but I cant use it my accounts are not working
