Bill

[Oh1]

Can someone please explain why my bill is so much higher than last month?

@Oh1 This is not O2. This is a customer community. You need to speak to customer service.
Call 202 from your mobile or 0800 032 1402 from any phone or numbers here: Guide: Coronavirus Community Help and Support 
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.
Say 'Upgrade', 'Lost/Stolen', or 'Fraud' if the suggestion above doesn't get you through.
Best time to call is 8 am.
You can also reach O2 via social media:
Facebook (https://o2uk.co/O2CFB), Twitter (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)
Or you can call them on 0800 081 0255

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 Guide: How-to guide for My O2 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.
