FNB Debit Order Reversals during COVID-19 Lockdown issues

I really don't like doing this but I think I need to put it out there that FNB now allows merchants/service providers to put through debit orders in your account which you never authorized! To compound issues, COVID-19 gave FNB the best hiding position to say they can't help you with Debit Order reversal but you have to use the App. Sure! I go to the app and they are trying to help me with a loan! Somebody put in a debit order of R1,400 on 01/03/2020 with the reference MULTID FORAANDG***. I reversed it. Now on 01/04/2020 they doubled it (R2,800). I have been calling FNB for a whole week now, being sent to they Chat service on the App which takes me to a dead end for 2 weeks now! I would seem the consultants who answer the phone also have no cooking clue how the reversal during COVID-19 works! One actually (get this!) told me they've just updated the option for COVID-19 and they just came out of the meeting and it now allows you to reverse Debit Orders. The sad part will be after 40 days I won't be able to reverse it again. Also, FNB charges one for reversing a debit order, even though you didn't authorize it! How does this work?
