write pas tense paragraph about lost something

yesterday I lost my wallet while I was at the mall, finally i reported it to the security guard that is around it. 30 minutes later,  finally i found my wallet, which was already taken by someone else when the wallet fell. finally I thank the security guard and I immediately went home.

kemarin aku kehilangan dompet saat aku berada di mal, aku akhirnya melaporkannya kepada satpam yang ada disekitar situ. 30 menit kemudian, akhirnya aku menemukan dompetku, yang ternyata telah diambil oleh orang lain ketika dompetku jatuh. akhirnya aku berterima kasih kepada satpam dan aku segera pulang kerumah
