No clue to what she is doing Nedbank App lady

I have been going to the Nedbank branches for many years and have gotten outstanding assistance. Since the new Nedbank app has been introduced. There has been a lady known as the "Nedbank App" lady at the Menlyn Mall branch. I have notified her about the fact that we can't buy Telkom airtime nor data using it. Numerous times I had to show her the problem/error I get. My patience ran out because It's either I'm slow or she is slower than me.She kept saying why not use the old one. Or use internet banking. What is the point of have a new convenient app when I still need to logon to the internet and do simple transaction that take less than 5 mins. I really don't see the point of having her there. She clearly is *********** and doesn't have the passion for people and probably has never used the app herself. I would expect Nedbank to take such people to training for people s**** and technical s****s. To add on, before a product is released aren't there tests performed? A simple cliche like this can cost the bank a lot of money. Have the problem checked and fixed. Both her and technical.
