Can't link VM account to VMO2 ID

I can't link my VM account to my VMO2 ID as I cannot login to my VM email account.
I follow the instructions for linking which involves a link sent to the email account I can no longer access.

This is maddening. I could only pay my bill as I have the app on my phone.

I can no longer access Sky Sports through the app, nor can I watch anything on VirginTVGo.
