Nedbank MFC duplicate debit order and making one go in circles

Nedbank MFC I find myself so astonished and disgusted in your service. Previously the service were up to standard and I was impressed and telling everyone about how good and on top of it the team was. But this time around. When my debit order didn't go off on the 25th of June. You wasted no time to contact me. Now. You too my debit order twice. I have emailed with the dates,the amount, my account number and ID. Only to be told I must prove it by sending a statement. I then advised them. They should update my statement and send it to me. Because why should I need to prove it. Why should I make all the effort when they made the mistake. I am disgusted in how this has been handled....or rather the lack of them handling it. It is still unresolved. All I get is emails asking for my ID or emails telling me the email has been sent to the relevant department. I am wondering if the relevant department still exists. Looking at all the 1star reviews. One must wonder. What is going on at Nedbank MFC. This ********** lack of customer service is not what I am accustomed to from Nedbank MFC. Sies.
