I cannot escalate my dispute to a claim

Description

Good day. I filed a dispute for a product I purchased on Mar 7th. Unknown to me it was from China. 3 weeks after I filed a dispute the company replied with a Tracking number » I’ve still not received my product. (A N95 mask) 1. When clicking on the tracking number a chinese web site comes up. Nothing in English. When paying by paypal it showed the payee as the company on the order page but the PayPal transaction page shows some weird chinese payee. 2. When I click on the « Check status » link from my email receipt the page is gone. 3. The original ‘company’ is now under some odd company I’ve never heard of. When I go to the « Resolution Page » it show the dispute but I cannot escalate to a claim. Can someone please advise me? Thank you. »
