Unauthorised debits orders

I’m so upset with FNB, I’m tired of these unauthorised debits foreign T 412752*961 , that keeps going off on my account what’s worse is i keep losing money that I Dnt have if they bounce , I’ve incurred charges more that 800 this month already cause the debit keeps bouncing , I’ve reported it multiple times and nothing is happening I’m really also considering moving to another bank cause wow, this is not on🥹 I’m Sidney Nortje ***
