Account number and Area ref

Hello

I've had my 500mbps internet installed on the 17th January but have not received no welcome email or letter with my account number on it. The last time I was on here (for a different issue) I was told I would receive an email about my bill on the 29th January which would have my account number and area ref number on it but I haven’t received it. Is there any other way of getting my account number and area ref number so I can make a virgin media account so I can manage my bills and direct debit.

Thank you
