I should have read and listened to the most recent feedback on this seller.
A lesson learned.
EBay has a deadline for Disputes and Claims of about 30 days from projected delivery date.
Another lesson,
NEVER accept an offer of a replacement. As you have learned it won't arrive either.
And a third lesson.
Go to your Paypal account and start a Claim there.
You have 180 days from payment for this.
