Windows 11 Activation Error code: 0xC004C003

I just paid to upgrade my "Windows 11 Home" to "Windows 11 Pro" via the microsoft app store. However, after installation and restarts, the activation isn't working. I'm receiving error code: 0xC004C003. Also it says "Windows 11 Enterprise" at the top of the activation settings screen not "Windows 11 Pro" for some reason. I have the receipt but can't find any way to contact an actual microsoft support human. Any help would be appreciated.
