First come back and hopefully you are still in time go top right to the little down arrow select Edit and remove your address details from your post above. This is a public forum , and it's not safe to leave such details.
Were you expecting an eBay delivery? Then, open a case for item not as described, and if the seller does not respond with either a refund or a postage label to return what was received, escalate on day 4, eBay step in and force the refund.
