Lots of issues currently.

Try online https://mymobile.o2.co.uk/
If using the app, try deleting, rebooting phone and then reinstall the app.

You need to contact O2.

Not seen that one for a while @ralman 

There are other threads about this on the community.

One post has a slightly different website to use:

From memory, as it has been a while since this happened for me and I am now on the "new" customer platform, here is what I had to do.

Make sure you are using a browser with no cookies (or use an incognito mode).

Go to the web above (accounts.o2.co.uk) - this may or may not generate a 403 error. If it does delete the accounts part and try again.

Enter your log in details.

On the next page, click the image of a phone in the top left, and then click on your phone number.

When the page loads, click on the view bill link and then choose the bill you want to see.
