Hi,
In situations like this, the first step is to reach out to the seller directly through eBay messaging. Politely request the tracking number from them, explaining that you haven't received it yet and you'd like to keep track of your package.
If you don't receive a response from the seller or if they are unable to provide the tracking number, you can contact eBay customer support for assistance. They can help facilitate communication between you and the seller or provide guidance on the next steps to take.
Additionally, if the estimated delivery date has passed and you still haven't received your package, you may be eligible for a refund or replacement under eBay's Money Back Guarantee. Be sure to keep all communication with the seller documented and follow eBay's guidelines for resolving issues with your purchase.
I hope you're able to get the tracking number and receive your package soon.
