Bad banking

I am deeply dissatisfied with the way that discovery is handling their banking affairs. I received a payment and transferred the funds to one of my other accounts with another bank. They needed me to confirm the payment. Since i have been on the phone trying to confirm this and they have blocked my account and my app. When i call them i need to auth its me through the same app THAT THEY BLOCKED. in essence i cant get through to them on their call centre line becoz i can’t authorise on the app they blocked. get one of your damn people to call me today still .
