How to change admin ID

How to change admin ID

We want to create a specific new ID for managing all software stuff including zoho apps. I have made a Typo error in the email id while creating Zoho creator account. Now i want to get my  receipts and change the ID too. Fortunately i have created other users so usage may not be the problem. However I need to change the admin ID for communication needs.

Even if i choose forget pwd option, a mail will be triggered to non-existing email which is of no use. 

How to do it?
