You need to contact O2 to correct your number on the system.
All ways here Guide: How to find help & contact O2
Guide: A Guide to Skype if needed to call.
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.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
