FNB *****ing my money

On 5 December R1940 was marked for an "Outstanding Debit Authorization" on my FNB easy account, there's no trace whatsoever of any transaction I've done, not even a listed pending transaction. 3 Months down the line they've taken an additional R380, now its R2323 just taken off my account with no trace whatsoever. I think you're better off with your money under your bed than with them.
