FNB Digital Banking security is suspect

On the 24 February FNB notified me that "For enhanced security, email notifications will be decommissioned for all app-linked customers, who will now receive inContact notifications exclusively on the banking app." I'm still receiving email notifications and I wasted 30 minutes on Secure chat, with 3 agents (Orreal, Tyrone & Jamil), who seemed incapable of understanding my query. This is an FNB Digital Banking feature, not something requested by me as an individual, to enhance their clients' security. That being the case, why has it not been implemented almost 6 weeks later. ****s & internet ***** is rife, so all necessary precautions should be taken.
