Pathetic system

My daughter has 2 Nedbank accounts. Now she lost the card for the one and this morning using the Nedbank app cancelled the wrong card blocking the wrong account. Now we have a situation where the wrong account is blocked. She phoned to reverse this and they said there`s no way it can be reversed. My problem is she has money in that account plus there is money that gets credited to that account for her varsity studies. Surely there must be a way to unblock it. I`m sure she`s not the first person that has made this mistake. I want a solution to this problem as we nearing end of the month.
