Welcome to Virgin Media and a very warm welcome the community forums! Apologies for our delayed response.
Glad to hear everything went well with your installation. You should have received your welcome email by now, have you checked your junk and spam folders? Sometimes they can be hiding somewhere in there.
Your account number and area reference will be shown on your bill, however if you still haven't been able to locate your welcome email or get the details you need just let me know and I can get that resent out to you.
