FNB taking youth account money

My daughter has a FNBy account linked to my banking profile. On 30 April 2024 FNB transferred my daughter's savings out of her youth account and closed said account. FNB gave no notice before doing this. After numerous calls/requests/e-mails/forms to FNB, FNB customer service, Private banking analyst etc the money is still gone. I am told I should be grateful for the assistance I have gotten so far. Give back my daughter;s money FNB!!. It does not belong to you. The money belongs to your 11 year old client who you have ****** of her pocket and birthday money. It is the 6 June, no money...no feedback. Who can help with this type of thing? Strange how FNB knows exactly where to deduct their fees every month. FNB knows exactly where to e-mail price increases to. But FNB cannot contact a client before they just take their money from their accounts.
