Air France lost bags nearly 3 weeks ago

I was traveling Air France and two of my bags were delayed so I got home to America without it. The next day (nearly three weeks ago) I got an email saying my bags had been loaded onto a plane from Paris to JFK and would be delivered to me soon. That same night I got a bag, but only one. I was confused so I asked the driver and he said “maybe tomorrow” since then Air France has told me everyday they have no update and either don’t know where the bag is or don’t have the info yet. Now for the last week they’ve been saying it’s in Paris but hasn’t been sent yet. They have no way of contacting the baggage team other than internal messaging apparently and the bag team hasn’t responded to any of their requests. JFK baggage team also requested the bag several times as well to be sent. I normally wouldn’t check that kind of bag but I had to last minute and it contains items that belong to my grandma who recently passed 🙁

Anyone know who to contact?
