Really poor service

Today marks precisely two months that went missing out of my account and still FNB as a bank denies any responsibility from the 7th of July up until mid August I was isolated with covid 19 twice money was withdrawn from my account according to FNB because my card was in my possession they can't be held liable for any of the money that went out of my account money was withdrawn but I did not get a single notification whatsoever that money was withdrawn and until today I'm still fighting to get my money back as I'm the one who is being dragged to court for arrears which is not fair at all 19 300 out of my account and I must fight with FNB over my own money which I did not even enjoy
