You can edit your details through the Self-Service Portal and need not depend on your customer support team to do the same for you. It enables you to modify your own profile whenever you want and saves considerable time.
To edit your profile
Click the My Details tab on the header pane.
Click the Edit Contact button in the center pane. The next page displays your user profile as created/edited last time in an editable form.
All the fields except the Login Name and Account Name in this form are editable. Your name is a mandatory field in the form. You can choose to leave the other fields blank. You can also change your password using the Change Password link. Click here to know how to change password.
When you are done with the modifications, click Update My details.
