Fnb banking app, Fundaba

I have been having issues with my fnb banking app for 3 months now, I have visited 3 different branches, spoke to over 5 different consultants of which some didn't even know what I was querying. One consultant contacted me and I later received an email with a reference number for me to follow up on the status of my query, I did but never received a reply. It is frustrating waiting on long queues both on the phone at the branches only to back home with an unresolved issue.
