These are buyer and seller forums. You are not talking to eBay and odds are strong that your seller will not even see this posting.
Have you contacted your seller (either through eBay or paypal)?
What (if anything) did they say?
You are probably too late for an Item-Not-Received claim on eBay -- which is up to 30 days after last estimated arrival date.
If you paid with paypal, then you can file an Item-Not-Received claim with paypal for up to 180 days after Sept 5.
