Call customer services on 202 from your o2 mobile.
8-8.30am is a good time to call as the phone lines are a little quieter then.
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.Currently using:
