Very bad service with FNB

I’m very unhappy with FNB Gobabis service. I would most definitely not refer FNB to anyone. Before my husband settled his accounts at FNB he app**** for a credit card for me one his bank account. The payment of the card was duducted from his bank account every month. Then his business folded and he sold his farms to settle the outstanding amount at FNB. We asked the repeatedly if there was anything else outstanding and they kept on saying no. After the farms was sold and all the outstanding debt was settled they deposited the rest of the money into his account. Me and my husband was married out of community. And suddenly they started deducting from my account. Their reason is bescause the credit card was in my name. Now I have told them repeatedly I can’t use a card if its not in my name but he was responsible for the payment. At a later stage I changed banks because they even put a hold on my account so I cant use any off my money that comes into that I account. So clearly the rules dont apply. After alot of fighting with FNB I came to the conclusion to be safe I can use my husbands card as long as its not in my name even if the payment is deducted from his account otherwise I will be liable for the payment.
