why do I need a bank card to close my account?

Wen I got ther the lady asked what I was comming in for. I told her I'm closing my account and she said I needed my card to do that. I told her I had lost my card and she then said I would need to pay R50 to get a card so they can swipe and close the account. I told her I'm not paying R50 just to close my account. Anyway she send me 2 a lady inside who basicvally said the same thing. Why must I pay R50 for something I'm not going to use?then I saw another guy and he said that too! I tink it is absolutely ridiculous that you need the card to close your account anyway.why can't we just use our I'd. I refuse to pay the R50 and I am not responsible for whatever charges are going to be adding on to that account from here on it is not my responsibility as I have approached them to close the account. They said that there is nothing else they can do. We go to the bank seeking help and the people that works there can't help me? They just look at me saying I mus pay I mus pay. I DON'T want to pay for another card just to close my account. Management needs to train people to provide a proper service and not just look at you not being able to help me at all! I want my account closed. That's al
