FNB Non Service during COVID-19 lockdown

COVID-19 has really been a very frustrating thing for me as an FNB client! A school keeps putting through a debit Order for Boarding fees when my daughter is no longer in boarding school. To reverse it I have to talk to the school and guess what, the schools are still closed! FNB keep sending me to the secure chat on the App and today I was number 636 in the queue! The App will automatically log you off after a a minute or so of inactivity and when they respond you're back to square one!
