Ehydra/Enhydra

Curious of how I can change my name to Enhydra as I have forgotten the "n" while signing up, also noted deleting accounts are impossible, I only have 1 phone number so creating a new account is not possible either.
Seems I have a situation here, I'm stuck as Ehydra, I suppose it could mean E-Water, scientifically, yet I'm not so sure about it. I'd love to have some feedback with this, possibility of some help, maybe someone else figured out how to delete accounts so I can be who I want to be on this developing site.
