If no luck with those options the loss must be reported to O2 within 24 hours. That way, the customer can only be held liable for any charges up to the point of reporting or a maximum liability of £100.
There are various ways to do this and the links are provided below. Just remember to have your account details handy. Here the info required when contacting O2 to report a loss:
Mobile number –
If you want to make an insurance claim, O2 will need a few more bits of information around the incident (explained under the help page). It’s always good to confirm the Handset make and model
IMEI isn’t necessary, but helpful if you have it available.
(Remeber to stay on the line right through to the end of the recorded announcements and options)
The Voice option is 24hrs, so if it’s in normal opening times it will go through to CS. If it's outside of these goes to the Out of hour’s team who deal with Lost and Stolen queries.
