Hey @Arthur7,
Welcome to the forums and thanks for your tweet. Sorry to hear you've lost your email account this week.
Unfortunately, we are unable to retrieve email accounts that are no longer tied to an active account with us - these are what we call 'orphaned' accounts and this usually occurs around 90 days after disconnection of services, however some are often accessible for longer.
If you do have a different, current account with us then we could try a Move and Transfer of the email, which would re-register the email with the current account using all your old details.
If there is no current active account, then unfortunately we wouldn't be able to offer further assistance here. Apologies for this.
The advice given above by Sololobo in their previous post may help.
Kind regards,
