FNB incapable of stopping Netflix helping themselves to your bank accounts

Netflix continue to take money out my credit card even after advising them 6 months ago to cancel . They simply ignore it and find a way to take money with out authorization, so I contact FNB Private clients, secure chat , it takes about 29 minutes for them to respond but it is as usual not helpful nor advise to resolve it , eg they say you must advise Netflix to stop , Hullo what do they I tried doing for 6 months , so instead of blocking it they say no you must cancel your credit card and apply for a new one ? So when you ask them so you want me to have to go through this long lengthy process instead of having a facility to block unauthorized taking of money from my account , this is to much to comprehend the banker just signs off incapable of answering the question. This same thing happens everytime, so one has to wait till the next day and spend 3 hours dealing with a live PB ! . I don't think there is a competent supervisor at FNB it's beyond pathetic.
