Debit order reversal nightmare

this is the most useless bank i have ever used and i cant believe am even saying this because my husband used to tell to leave it but i have used fnb for many years .Now is the right time to leave it , firstly they take away the option of reversing debit orders on their app and not tell customers,secondly their app takes 30+mnts to open .i have spoken to my creditors not to debit any money for 3 months and we had an agreement but debit orders still went through so i was adviced to reverse them and i went to fnb to do that since their app was not helping.I went ot fnb on the 4 /may /2020 to reverse the debit orders of more than R3000 and they told me to apply under covid19 icon i did that same day but till today there is no money in my account and they told me it would take only 24hrs, fnb has put alot of options on their appp which they know very well they dont work cause i tried to check the status of my application it shows nothing has been done or it doesn't show the status .

FNB should know better ,at times like this they should be helping their customers not depressing.Why the hell do we have their app but still cant get any help from it, Even if you call them you stay on the line and an hour later a machine tells you they are unavailable.Because of this pandemic i desperstely need this money but fbn couldn't careless. What would it take for my money to be reversed or what must i do to get my money back? FNB THE MOST USELESS BANK. You should ask CAPITEC AND STANDARD BANK HOW THEY KEEPING THEIR CUSTOMERS HAPPY maybe you will learn one or two things from about customer service.
