@Tracy15 This is not O2. This is a customer community. If you want to speak to customer service call 202 from your mobile or 0344 809 0202, 0800 902 0217 (Payment Management) or 0800 032 1402
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 (now X) (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)

@Tracy15this is my philosophy

If you don’t know who it is and there is no message delete it. Beware of scam calls always.

Never respond to offers from anyone saying they are from o2.  Go directly to o2 site.

Many have been caught with offers even from so called o2 partners and are unable to get out of an expensive contract.

Keep safe keep aware.

Good you asked here, best wishes 😍
