My O2 app

[Chloe131]

I’ve been with O2 for years and when I upgraded 2 years ago it won’t let me log on to the app as it says it’s not available to me yet. I’m also having trouble logging on to my O2 online as it says after putting in my email, password and the code that's text to me that the mobile number already exists.
