FNB atm sagas

Tell me why we are going through so much as FNB customers, from being offline and the app not working all day on the 28th Nov to today I tried to deposit money only for the ATM to say deposit is being cancelled. The money was not returned. Slip reads your deposit was unsuccessful T550 TRACE. What is this when we have emergencies, my goodness? Limited options when you call. Told to go to a branch. What in the time wasting Tom foolery?? Honestly need to change banks.
