HOW DO I CHANGE MY SUBDOMAIN NAME ?

There is no direct way to change it. You have to delete your subdomain and sign up for a new one. Let's say you registered blue.coolhere.com and would now like to change it to red.hothere.com, then you must delete blue.coolhere.com and apply for a new red.hothere.com subdomain.
