I can't view my O2 account

I want to look at my data usage but can't get into my account. I have changed my password but it still won't open

Can you log in online https://mymobile.o2.co.uk/ ?
If so, try deleting the app, rebooting your phone and then reinstall the app.
We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this
Thanks
