FNB failed me

So on the 29th of May 2018 I sent an email to the FNB debit card disputes department to request a reversal on my business card's online transaction that had been reserved because there was some seemingly ********** activities going on on my account from the service provider I had just used. I even cancelled the card i had used. FNB approved my claim about 7days days later and reversed my transaction (great right? Not for long!!) The next day, FNB went ahead and allowed the reserved amount to go off my account despite having reversed it and I had already used that reversed amount resulting in my account sitting in a negative. Since the 12th of June I have been querying this matter and at first they sent me from pillar to post, & then about 1 week ago they told me to get a credit note from the ********* in order for them to fix it (what a joke right?) What ********* is going to give you a credit note for u to be refunded for his ********** activities on your account? ?? Nonetheless, I have since dealt with Cestor Davids at FNB who, a day after asking me to resend ALL the documents & info I sent to their disputes department, then told me that he was no longer dealing with such matters and referred me to Emely Bogopane at FNB. Unlike Cestor, Emely hasn't even responded to my communication. It's been 2days now!

For a bank I thought was great in terms of customer service and tech, they have really ****ped on me this time. This has been going on for almost a month and I'm very frustrated at this point. Coming to this platform is my way of just warning others to be careful of such disputes because you might end up receiving the same "not my problem" attitude that I am now getting.
