If the Find my phone or send the last location was not activated then Samsung can't assist unfortunately @Miket_09
Contact your mobile network to have your sim stopped and the phone imei barred.
If you have insurance then one kf the criteria maybe to contact the police for a crime number.
If your phone wasn't locked via a fingerprint etc then change your passwords just incase.
I wish all the best.
