I have had nothing but issues for months with this app. I have been a CUA/ Great Southern customer for over 20 years without issues. Now I cannot login in via the app, since an update a few months ago. it's now a pain, and have to go through mobile website, which is hard to use on a phone screen. talked to GS, if I can't get a fix, my next step is to move... I have the same Android phone, everything works seamlessly. Something needs to happen, or we will leave.

I spent three hours.... This follows on from my first part. In their app they want customer number. For me to find it I need to quit the screen and lose all my input to date. It's 2 am and I am in hospital. Did I mention I am mad. Send communications through the app. Get to the end of the script. They want my member #. I am in their app. At least give me option to insert from a drop down list. Better still ask for information at the very start. Quite screen. Email wife " I give up"

Hi John, sorry to hear of your situation. To understand the issue you are facing better, could you please send us an email to app.support@gsb.com.au? If you only require your customer number, please call 133 282 instead, select option 3, then option 3 again and we can help with getting your customer number! Thanks, Great Southern Bank
