Discovery bank is beyond useless.

I am over disgusted with the lack of service from Discovery Bank. To everyone reading this, discovery bank service is in the gutter, useless as hell with no one willing to assist. I've spent hours on the phone trying to get help with my banking app that suddenly does not recognise my face. Has my face all of a sudden changed in the last 2 months? I need this resolved asap. I can't keep waiting on the line for an OTP that only gets sent to me 45 minutes later when it's meant to be instantly. The last person I spoke to was a useless Lebo who refused to give me her surname and refused to escalate this to her manager Vusani. This is my call reference ***5.
