If you need help undeleting your previous account that was deleted in error, can you contact us and include the account name and the email that was on the account at the time of the account having been deleted? We'll be able to look into and getting your account restored and follow up with you should we need to discuss anything more to get this resolved.
I'm requesting you contact us via that web form so that there isn't any sensitive account related information being shared on the forums.
