my bill has more than doubled

[ShirlR]

My bill has more than doubled.

It was around £14 and the last bill is approx £35.

I would like to know why as I haven't used my phone any differently to usual.

Did you have an offer that has ended on your account?

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 

https://community.o2.co.uk/t5/How-to-Guides/How-to-guide-My-O2/ba-p/1275603

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
