If it has not updated, and you are unable to make calls, reach out to O2 on any of the ways in here, @beth19 - Guide: How to find help & contact O2
Social Media Team, using Facebook Messenger or X/Twitter are a good team to reach out to, and ping them every so often until you get a response:
Good luck!
