Xbox All Access Upgrade

I was lucky and able to preorder and Xbox Series X yesterday using Xbox All Access through Gamestop. I currently have a line of credit for my existing Xbox One X and wanted to pursue the upgrade option. The upgrade instructions say that Citizen One will
send me an email asking for my intent to upgrade, however it looks like the line of credit for my Series X was created with the shorter version of my name (Jeff vs. Jeffrey). Same SSN and all other info though. Is there a way I can confirm I did this correctly
and that I just need to wait a day or two for the email from Citizen One? I contacted them and they said they didn't know. I may just be jumping the gun, but want to make sure I don't need to cancel my preorder.
