Absa online banking department - no serivce

I got a new device and tried linking it to my online banking. The part of the web portal that links new devices is broken. When I scan the QR code it returns an error, but not without unlinking my old device. Now my internet banking is unsecured, no verification device.

So I called digital banking (at 16:30) for some assistance and every time the the phone menu says I'm going through to an agent, the call gets cut off. The new office hours is only till 5pm. At exactly 5pm I call lost cards since they should still be working. I manage to get through to an agent (at 17:01 - I was watching the time, hoping I can still catch someone in the office) and she tells me the entire digital banking department has left already, all of them, even the team leads. Nobody left to take calls. So you are telling me that none of the agents in that department took a call at 16:55? That is statistically impossible. So now I know why my call kept dropping right as I was put through to an agent, it was close to closing time and they all want to go home.

I was forced to call ***** and lock my internet banking since I no longer have 2 factor auth enabled.
