Unhappy customer wrong info

Very upset with fnb my card was giveing me problems so I go in to the branch to ask how much it would be to replace it as I didn't have money in me I just wanted to know the price the lady said it would be R90 to replace the card but if I order a card on the app it would be free and it would be delivered to me so I asked her if she could help me with this she said yes she told me to just log in to my app and I did then she did the rest and showed me it was ordered then today I see on my account a amount of R140 for a card replacement fee so I did go back to the same lady and showed her at the fnb branch and she said she remembers me and told me to wait she's gonna find out by her Manger then she comes back telling me sorry she made a mistake that day and it's not for free when you order it on the app my point is this I was given worg information so it's not right that should be paying for her mistake I can't afford toose R140 because of her mistake if I knew it would be R140 I would have Nver ordered on the app a card she said it's free this is unacceptable form FNB
