Virgin cancelling my email account in 30 days

Hi all,

I've seen some previous posts about this but no concrete solution. Essentially, I have a .net email account that my dad set up for our family of 4 in the 90s when I was born and I've used it ever since. However, I've been sent  this email:

"Hello Tom,
Following on from our earlier email, this is the final reminder that we’re closing your Virgin Media email account. This means you’ll lose access to your Virgin Media email address in 15 days. After this date the contents of your account will be removed and permanently deleted.

We’re closing your email account because you no longer have Virgin Media services.

Please make sure you do the following prior to closure of your Virgin Media email account:

Send any important emails or contacts to another email address

Save any attachments you want to keep to your computer or device

Let all your contacts know about your new email address
Tip: look for the archive and mail forwarding features on your new email – these can help you transfer any emails you want to keep.

For more help with managing your emails, please head here.

Kind regards,
The Virgin Media team"

I have no idea what to do because my entire digital life is based off of this email and I'd rather not have to transfer it all over to a new one. I understand that you might need to have an active virgin broadband account to save it? I have had Virgin broadband in the last 12 months but cancelled the subscription when I moved out of my old flat. My account area reference is 34 which is another thing I've seen mentioned.  

Any advice would be much appreciated!
