Hello, I am currently 16, about to turn 17 in a couple months. I still haven’t received my NINO but whenever i call, i would be sat there for more than an hour just waiting for someone to answer and no one ever does, and i even called from 3pm till closing and noone answered. I also moved houses recently so i need to have that changed on the system too but i cant ever get a hold of anyone.
