A Microsoft file hosting and synchronization service.
Hello
In fact, I want to add that it can take up to 48 hours, not 24 hour.
If it has been more than 48 hours, you would need to contact Microsoft billing support. To get help, open the "Get Help" app on your computer (just search for it in the Start menu). or go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Microsoft 365" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.
