Hi there I’ve actually rang the great Southern bank today. They told me that it is from their end and their tech peeps are onto it like now! I have a feeling they are kicking back having a party this bs has been happening now for over 6 weeks. 🙄. I am Not happy either. 
the bank said you can down load your statements and add them to your quickbooks. My accountant is not happy and I have to say neither am I! Good luck.
