Upgrade

[Ryanp]

I’ve had a text about upgrading in store and O2 will make up the difference. However I can’t see anything about it online or on the app

You need to call customer service
Advice from an O2 Guru to get through:
If you call 202, when it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Choose the fraud option if necessary
