Item tracking delivered to wrong Address

I bought an item . I believe I have been scammed. 

The tracking tells me delivered. But the address is not mine. 

I put the correct address on my order. 

The seller has not responded. 

What do I do? The item has been marked as delivered in ebay. But clearly not to me. 

The seller only recently opened the account. Has 100% rating on 5 reviews which I now beleive to be fake. 

What do I do next? Ebay wont reply. There is no option to open a 'did not receive ' dispute because it has been 'delivered'.
