I'm afraid that admin cannot be changed for your order at the moment, however you can add more administrators from the console. You can also consider to reorder with the correct email address.
To add more administrators, see help here - Manage your Creative Cloud for teams membership
We do not have more access to the e-mail of the main administrador, but we do have other administrador on the team account. There is any problem with that? We can keep with this e-mail as administrator or we should create a new account?
