@Denise70 O2 has been having an ongoing issue with this. I don't know if they've been able to fully resolve it yet, but try this guide and see if it helps: How do I get to the 'Download Bill' page? (o2.co.uk)

I've had a lot of success following these steps @Denise70 just in case you want to try something else.

I use Edge, and make sure that the option to clear all browsing history and cookies on exit is ticked.

Open a new window.

Type in the address "accounts.o2.co.uk" - this generates a 403 error.

Remove the "accounts." part from the address and enter. o2 website then loads.

Click on my o2 and enter my details.

Click the image of a phone next to my number (top left just under the main banner).

Click on my phone number.

Then choose "bills and current charges" and "view airtime bill".

Then click on "download and print latest bill".

I then get another tab/window open with the normal bills menu on the left (previous bills, recent charges, etc).

I have 2 pay monthly accounts. One downloads the latest bill but the other produces this error message "DASH_ERR04: The account number in the target address is invalid".  Any help please ?
