FNB Aiding ********** to ***** our money!

On the 30th of September there was a ********** debit order amounting to R646.94 that went off on my account. I attempted to reverse it using cellphone banking but was directed to the app. I have been attempting to reverse it on the bank app for over three weeks now and it doesn't allow me to reverse. I get an error message saying the debit order cannot be disputed at the moment. I have called the premier banking line, the app line and have been getting no assistance. Phone lines are robotised and no option to talk to a consultant instead you get lead back to the app and a voice recording saying that debit orders cannot be disputed at that time and I should use the app. I even went the twitter route and reached out to the RBjacobs account. No assistance, simply recommends the same platforms I've already tried using and gotten no joy from. This is very frustrating. Money was ****** from my account and I am being barred from recouping it! FNB is aiding ********* in this!!!
