NAB Middle Brighton branch to deposit $5,500 into one of the ATM/exchange machine. I did not know that the machine can only receive 50x bank notes, so I put 38 $100 bank notes and 34 $50 bank notes. They swallowed my $4,400 but spilled out $1,100 which I finally deposit to the cashier (Tess) However the machine didnot record my $4,400 deposit in my account,or give me a receipt. Tess helped me to write an escalation email, but went to the wrong department. I came again to the branch on 28-Aug and the case is now with Melanie who has been very helpful, but unfortunately NAB still yet to resolve my missing money after more than 3 days. Bad experience using a deposit machine! DONT USE the deposit machine!
