Money Disappears From My FNB Account Without A Trace

Just lost R80 from my FNB account without any trace, it's little from me but fnb has over 8 million customers at the moment imagine *****ing that R80 from just half of those. That is R80 x 4 million which is an easy R320 million in someone's account just from *****ing from clients. You call it...... Its not the first or last time it's happening, I have pictures to prove but no option to upload them.
