None Operating Contact Centre and App

I am losing my patience with FNB. I have been trying to call them since Friday and alternatively trying to chat with a banker on the app. I have spent a lot of money trying to hold for a consultant till I ran out of airtime not once 4 times. The online banker on the other hand. You wait for them to respond then this morning the one greeted and never responded again. Then by the time a new consultant responded I have something else to do. Then guess what I have to queue again. Literally since Friday I have been at this. Just to reverse a debit order. My question is one. If during lockdown they are working they why the lack of efficiency??? No man
