REPEATEDLY every month when I need to pay bills cannot sign in

called support 5 times one woman hung up on me

NO ONE CAN HELP SOLVE THIS ISSUE

I am seriously planning on changing banks I do not want to do my banking on the small phone which will let me sign in.  Why give a reference Number if support does not even ask for it.  This has happened many months in a row it will eventually solve itself yet I NEED TO PAY MY BILLS when I HAVE ENERGY to PAY THEM not when the bank says I can nor tell me to use the small phone.
