Can’t do the Device link for Internet banking

My business has been standing still, cause no ABSA bank can generate a security code to have my phone linked to my profile for internet banking. Apparently this is going to take a long time to fix, I was told at ABSA in Flora Centre.... so I can’t do any internet banking until who knows how long and so it’s okay for my business to stand still....... Really Frustrating that we must battle like this. Poor service.
