Absa can't provide the basics with regards to the app

The Absa app is nonsense I've been trying to link my app to my card for a week now it's very inconvenient and I really don't know what I am paying for I can get bank charges of R500 a month but still have problems what am I even paying for I use my 40 Rand airtime which was for lunch hoping to call the call centre so I can get cash out of my own account and the call centre can't even assist I have to go to the branch it's 2019 why can't the call centre help me my branch closes much earlier than the other banks on a Saturday u would never recommend Absa to anyone
