FNB ********* business practice

Do not let FNB fool you that they are tentative in customer service and vigilant against bad business practice. FNB have transgressed in allowing ******* activity on my account, from their own part. They put through / authorized a payment to go through 2 weeks AFTER my was reported ******, and and canceled. Cancelation date was 25 August. The payment authorised on the canceled card took place 10 September. FURTHERMORE.... I have absolutely no overdraft, which FNB authorised a debit on my account of an access of R26,400 rand. I have contacted my attorney for legal advise, and although I have spent more than 2 hours on the phone with FNB, and them promising that a manager will contact me, they have just brushed me off.... 2 days and not 1 phone call from FNB. THIS IS THEIR error, not mine... and yet, they just don't care. This is my first step un contacting the media and blowing this whole thing out the water
