Original Title: child account

I am trying to setup a child account under my account.  But I keep getting this message when I provide credit card information to verify I am an adult: We're unable to complete your request

Microsoft account is experiencing technical problems. Please try again later.

I have heard lots of people get this and other blogs seem to indicate I need to have something done to my account by Microsoft so I can actually perform this step.  Is there someone from Microsoft who is able to assist?
