Fake AirPods pro2 usb c in orginal Box

In the store they say they can't do anything because I should have unpacked them there so they would see that the headphones are fake, they don't believe me like this. I understand that when a product is manufactured at Apple directly, it is their responsibility, but an original packaged Apple product, wherever purchased, should be directly connected to Apple and I can certainly check where the headphones are activated, just like with the iPhone. I wonder where the headphones are activated. I saw on the Best Buy forum that I'm not the only one, there were fake headphones several times. Apple can certainly check through my Apple ID that the original headphones with that serial number are not with me, but who knows where they were activated. This needs to be investigated, who knows what else happens during packaging with other Apple products.

Serial number is in the picture below.
