Tobi isn't helpful AT ALL!

I have tried endlessly to get hold of a human at customer care in order for me to update my banking details. I keep getting redirected to the BOT thing regardless of the options I choose. This system is not helpful at all. Even the customer care email comes back stating I must make use of this Tobi. It will even ask if I want to speak to an agent and I reply "yes", it then says it can't assist. What is the point. Wasted so much time today.
