Hi Pritca, welcome back to the community! Thank you for posting.
I can certainly look into the account and email addresses you need deleting. Thanks to Coenoby for their advice whilst we picked this up.
If you still had access to your My Virgin Media account you would be able to delete the secondary emails, however as this is not the case we will need to raise this on your behalf.
I will send you a PM to confirm a few details and get this sorted for you.
We can return to the public thread with an update as soon as possible.
All the best!
Molly
