Banking App system not available NO ASSISTANCE

My banking app has not been working for longer than a week. I get the message that the system is currently unavailable. At some point it said my card was blocked. I went onto internet banking and had to change my log in details.

The number *** is an automated service that is useless. I phoned customer service and she put me through to an extension which just went silent. Then I tried to lodge a complaint online, which did not respond when I pressed the submit button.

My FOURTH ATTEMPT TO GET ASSISTANCE was an e-mail. They will respond in 2 working days I am told.

This is just not acceptable!
