Hi,
Please ask your question in the Microsoft Certification forum using link below. There are support moderators over there that will respond to your question in 1 business day and can assist with getting your certificate to show up:

NOTE: Passing MD-100 by itself will not earn you a certification. You need to also pass MD-101 (before it expires).
Please click Accept Answer if above was helpful.
Thanks.
