I have been charged £5 for 'things you've bought' this month on my bill. What is this for please?

@clarissa2 You can check your charges here: How do I get to the 'Download Bill' page? (o2.co.uk)

If you cannot see what the charge is for, you'll need to speak to customer service.
Call 202 from your mobile or 0344 809 0202 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:
