Problem changing license details

Hi, I would like to change some details of my license, city, address, but I can not find a way to do it. I already sent an email to support@unity3d.com, and the answer was: Login to the account is attached to the license, there you will be Able to change any details you wish. Sorry but I do not understand where I have access to change the details on the site since there is no login. Thank you.

From within Unity, select > Window > Asset Store.

In the Account Store window, find on the top-right a tab marked ‘Account’.

Click > Account > Log In. (then enter your details)

Now in the top-right ‘You’ appear instead of ‘Account’

Click > [You] > View Profile.

I see a billing address space here, hope this is what you were looking for.
