Lost iPhone

I lost my phone on February 20th, and I received this text from Apple today, 21st March. I clicked on the link but when I tried to check the last location of the iphone11 or where it was found, the phone never showed up. This device was removed from my ‘find my iPhone’. I didn’t remove it and it was still on lost mode. I don’t know what’s happened. Have the people hacked my things? Can anyone explain what’s happened?
