FNB KYC Bad Communication

Another KYC mis for FNB. My daughter's account was frozen because she turned 16 and must submit a copy of her ID within 3 months. This is good to know. FNB, please think through how to communicate with your customers before freezing an account! Maybe a popup message when I open my banking app. An SMS? Email? I enjoy being FNB customer, but the KYC communications is beyond unacceptable.
