Losing one's phone or having it stolen is a terrible feeling, not so much the phone, but all the personal data stored on phones today is expansive
Are you sure you lost it and wasn't perhaps taken without your knowledge? Calling Samsung support and giving your details, ngl but not one of your finest moments, neither is it something I would admit to and say out loud, You mentioned shortly after when you tried looking for your device again, iit was off the radar. Why couldn't they at least Block your phone straight away? Hopefully you went into Samsung's official page and changed your relevant passwords etc. Tracking it and physically going in search of it is dangerous and not worth it tbh I will say that "Find My Phone" on any platform is overated and full of flaws, giving one a false sense of security. Your cell network provider can block your IMEI With today's smart technology it is possible to remove a Google / Samsung account off of any phone in minutes, the iPhone takes a little longer.
Did you back up anything to the Cloud? One Drive, Google or Samsung? That's the only way to go about trying to retrieve your info.
