Hi Winter64,
Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
We're sorry to hear you're having an issue with your secondary email account. When requesting to get these closed, it will close any and all email addresses on the account. This is something we can certainly raise for you but in order to do that I will need to confirm some information with you to pass security.
I have sent you a direct message to allow us to do this with you in a private space. If you are using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you are on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊
Thanks,
