my bill

[Richard27]

My tariff is £12.90 but you charged me £25.80. Why?

This looks like something you’ll be able to do or check in the My O2 app. We have a guide to help with that if you’re unsure how to use it 

How-to guide: My O2 - O2 Community

And don’t worry if you get stuck because there’s an in-app messaging service you can use to chat with O2 who can help. Just go to the ‘Support’ tab and ‘Start a Conversation’ at the bottom.

If you still need help then the Social Media teams will be on hand, just send them a message
