If you give us a ring on 202 and when prompted reason for contacting say: Insurance Claim it will then ask if you want to start a new claim and they will put you through to the correct team.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
