need to reactivate my account

Hi,

I recently deactivated my corporate account, because there were no way for my "company admin" to invite me as a company user with me already having a account as it seemed. Now after I've deactivated the account my boss could send me an invite link. 

Unfortunately I couldn't create a new account using the same mail address as the account I deactivated (or I thought was deleted).

"Email address unauthorized. Please contact Customer Care."

Could you help me?
