Nedbank app causes poor customer service

I am a new client at Nedbank. Have had no issues so far except for their Money App. Although it is formulated to make processes easier it really does not. I would just like to say that you offer good service why not better your app service? Update it so there are less errors. Currently app**** for something but app cased delays...that will be another week of waiting. To better overall service please work on your technical issues on the app. Its not the first time the app has caused delays for me.
