It's a manual process and they received a high volume. I received mine over several weeks after registering. Just be patient and I'm sure you'll get them soon!
Thank you, @ChristopherCounsell for chiming in!
@ClariceGeo, as Chris mentioned, it's a bit of a manual process so please give us a bit of time. I'll reach out to the team to verify your GIS Day event.
Thank you, @BriannaEttley. I'll be waiting for a feedback!
