You bought.
You paid.
but when i bought next day seller remove it from the list
EBay shut down the seller?
No--because you still could Message him.
OK.
Now that could just mean that he ran out of stock. Does he have other items listed?
i didnot recive any item from him.
When did you order?
EBay gave you a 'last estimated date' for delivery. Has that passed?
If it has, go to the bottom of this page and open an Item Not Received Dispute.
The first suggestion is to Contact the Seller, but you have already tried that.
So. Go to the next step.
Ask eBay to step in and escalate to a Claim.
If the seller cannot prove delivery (not shipping, delivery) you will be refunded.
If the seller asks you to close the Claim "so that he can refund" do NOT do it. That's a scam.
If the seller promises a replacement, do NOT agree. That is probably a scam.
