FNB IS *****ING MY MONEY

FNB is literally *****ing money from me. There is literally about R1455 that's unaccounted for. They keep saying its from my transactions, but they cant show me these transactions and every time I confront the consultants about this and demand proof of these transactions, they just transfer me to someone else. Worse these "transactions" do not even show in my transaction history, so I cant even claim front. This money essentially just disappeared and noone can answer me.
