Hello Alien Notary,
Welcome to Microsoft Community.
It seems that you meet issue about OneDrive sync failure. I'm sorry for your bad experience. This can be annoying. I will try my best to help you. I have some advice for you:
- First, OneDrive sync can be reliable. If you are using OneDrive on PC, it depends on good network connection. You need shutdown your PC after it completes. You can confirm by checking a green checked sign in OneDrive of Explorer.
- You can sync again by click the OneDrive icon on the taskbar. Also, you can login into the web version of OneDrive to check if the sync is successfully done.
- What's the accurate meaning of your "information"? Are they document, files or Windows configuration? I don't know the precise situation of your OneDrive sync failure, please provide more details such as screenshots and error messages to me. So I can further know your issue.
- Should regard your word "return" as a refund? our community can't deal with problems such as account, bill and subscription. If you need more assistance regarding this, please understand that community members are also users like yourself don't have the ability or the right tools to looked into your account and issue refunds. So, it would be best if you contact Microsoft directly and have your return/refund request processed.
