GROUP: Lost & Found Property @ Heathrow Airport

AUTHOR: Hana Trần

Hello everyone.
On April 27th, I had a flight from Ho Chi Minh City, Vietnam, with a layover in Thailand before arriving in Jeddah.
Upon landing, I went through immigration and baggage claim, but my checked baggage and belongings were lost and cannot be found.
It’s a large suitcase containing clothes, medicine, and some Vietnamese items.
Please help me find a way to contact someone and retrieve my belongings.
