To be frank the seller is lying.
the item doesn't come as decribed
Did you receive anything?
If not, this is easy.
You can't get a refund through eBay, because they only allow 30 days after delivery or the last expected day for delivery.
I think you are saying that deadline has passed.
So go to Paypal.
The PP Resolution Centre is hidden under Tools on your PP account page.
You have 180 days from payment to open a Dispute.
If you did not receive anything, you will be refunded because the seller must prove Delivery (not shipping, delivery).
If he cannot, you will be refunded.
If he delivered something, but it was the wrong thing, PP requires you to return it to him WITH PROOF OF DELIVERY, to get your refund.
The principle is that neither the buyer nor the seller can have both the money and the item.
However.
The cost of returning the unwanted purchase to China* is very high. $40 or more.

PP requires the buyer to pay for return postage.
While some sellers might also pay return postage**
Calculate how much it will cost to get a refund.
Leave feedback.
The most effective feedback is calm and factual. "Sent wrong item. Did not send promised replacement." or 'Nothing received in spite of many promises."
The first suggestion in a Dispute is to contact the seller. Do not get into a conversation at this point.
You want your money back.
You never want a replacement. It either will not arrive or be no better than the original.
You want your money back.
*It is also expensive to the USA, but this is a known scam out of Asia. No replacement is ever sent, and often nothing was sent in the first place.
** And eBay requires this, another reason for acting quickly on problems.
