Debit Order Dibacle

So I've been struggling with FNB call centre, App and those Teams of bankers the whole morning. Spending MY airtime and time when noone knows what exactly I need to do. I tried to reverse a debit order with the Teams of bankers and Nqobile told me to call the call centre, when i call the call centre the lady who answered the phone put me through to a voice prompt which sent a link to my Banking app but when I follow the link I receive an error message that I need to call the call centre because debit orders above R200 cannot be done on the app. Now someone please explain to me that whose who at FNB banking cause this is just too unprofessional and just a pit how. Last month I asked the lady I spoke to to do a Stop payment on that referrence but the SAME AMOUNT AND SAME REFERENCE went through. I think what irritates me most is that noone is really saying how this works. I want this debit order reversed
