Hello Jade
Thank you for posting in Microsoft Community.
I appreciate you raising this concern to us and sorry to hear that you lost your Surface Pro 7 device. Unfortunately, Microsoft does not have the capability to track the location of lost or stolen devices. However, you can try using the "Find my device" feature on your Microsoft account to locate your device if it is still connected to the internet. See this link for more: Find and lock a lost Windows device - Microsoft Support
If you have concerns about the safety and security of your personal information, I recommend that you change your Microsoft account password and enable two-factor authentication to prevent unauthorized access to your account. Additionally, track every place you visited and report this to the nearest police station to conduct further investigation.
I really wish you all the best and hoping you'll find your device.
Best regards,
Rolando S.
