Hi TJN1066,
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've had some issues getting the support you need to delete these email addresses. This is something we can certainly check for you but in order to do that I will need to confirm some information with you.
I have sent you a direct message to allow us to do this with you in a private space. Just click on the little envelope at the top right-hand side of the page to access your inbox.
Many thanks,
