If you have paid, then it is up to the seller to refund you.
Contact the seller and ask them for a refund.
If they don't send a refund (you will get an email from Ebay when the seller processes it) you will need to wait until one day after the latest estimated delivery date and open an 'item not received' case.
Two points about using this forum:
We are other members like you. We can't access accounts or send you a refund.
You are not allowed to name other members in your post.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
