Welcome to the Community and thanks for posting on the Forum. I'm sorry that you are having problems porting your number. Apologies for the time it's taken to respond to your post. It's great to see that AlexKid has been able to give you some advice about number porting. Has this been resolved for you yet?
If the number port hasn't completed yet, please call in on 789 (Freephone from a Virgin Mobile) or 0345 6000 789 (from any other phone) or 150 (free from a Virgin Media landline) so that we can access your account details and check this for you.
