Bill without warning

<p>This morning when i looked FNB deducted R 2000.00 from my account to pay an older device account i have with them, My problem is that there was no arrangements made, not 1 phone call or email notifying me of this amount. I dont mind paying accounts but FNB cant just take any amount out of my bank account as they wish without any notice, I recently moved back to FNB because i thought they were a good bank, Ive spoken to 3 Different departments this morning then transfered to legal where there was no answer and only an anwering machine, i am sure the consumer protection act do protect consumers against this, but it seems like the banks ignore the law, i need this query sorted today.</p>
