Saving Account Detail update nightmare

I opened a Savings Account for my daughter more than two years back with Capitec. When she turned 16, they advised us that she need to bring her ID to update her account/ customer details and to replace my fingerprints with hers as per normal procedure otherwise they might place a hold on the account. So that we did. Since my daughter is still underage the Capitec Banking App was loaded on my cellphone device initially. Earlier this year I replaced it and the Capitec Banking App did not want to install on my new device. So off we went to our nearest Capitec Branch. This is where the nightmare started. Trying to access my daughter's account was no a problem. They have messed up my and her fingerprints on her account record when they updated it after her 16th birthday. They cannot access her account to rectify their mistake. They cannot close the account either because they cannot access the account. So we are stuck. I went back multiple times back to the branch (one or twice because they said they are ready for us to sort the matter out and we need to pay them a visit ) and then they start at step nr 1. "Lets phone IT". I will spend 1 hour generally the branch per visit and and when I had enough they are still on the phone with IT. So after visit 4 or 5 I advise they lady, enough is enough, she s not getting this sorted so please escalate. She promised to phone me on the next Monday to advise the progress but needless to say, 3 weeks down the line still waiting for that call. I have subsequently send an email to Client *** but I guess they don't really Care to much about that this specific Client after all. I received 1 response back after 5 days and advising me that the matter has been escalated to their Support Specialist for investigation and I can contact them again for any further queries. So I did - "what is your expected times lines?" - well no response on the query till today.

At this point I want the account to be closed. It is unacceptable that something like this cannot be sorted by the technical department of this bank. So so disappointed in this Bank.
