Mobile phone stolen

I bought a new unopened mobile phone. When I opened the package, I found that the swindler switched the Apple phone into a cottage phone. At present, we have notified the New Zealand police. I can get the mobile phone information such as serial number IMEI through the original mobile phone box that the swindler traded with me, and this is indeed an iPhone13 pro max. Excuse me, is there any way to help me and freeze the cheater's mobile phone?
