Hi,
did you pass an exam? When did you pass it? Note that it can take up to 2 weeks after passing the exam till you receive the email.
If you do not receive an email in 2 weeks, you should contact your regional support center (http://www.microsoft.com/learning/en/us/help/assisted-support.aspx).
Please have your exam printout ready when you call the support - they normaly need some information of this printout.
With kind regards,
Konrad
