Toal failure of service when needed

I installed the banking app on my new phone and used it for the first time on 03/08/2020. Everything was fine. On the evening 04/08/2020, the app locked me out, saying that I must phone the fraid number. I phoned the number the next day, to be told that I must visit a branch to verify my account. I tried to do so, but both the branches in Bethlehem closed at 14:00. My working hours does not permit me to visit the bank anytime before 14:00. I phoned the number again, explained the situation, but they would not help me. The operator said she will ask her teamleader to phone me, but this never happened. I needed to make urgent payments, but now I cannot as I am locked out of the app, locked out of internet banking and unable to visit the bank. Definetly not simpler, nor better, nor faster.
