跟美國lenovo購物用amazon payment沒收到 - 海外購物

我在6/24跟美國lenovo買我的筆電延長保固
lenovo網站顯示Status: Shipped on 06/27/2011
可是我一直到八月多都還沒收到,中間也透過Amazon寄了兩封信過去
到這禮拜申請了File Claim
Amazon寄了一封信給我:
The seller has confirmed that the order was sen to your email address on file
for this purchase. If they are not in your inbox, please be sure to check
your junk and/or spam filters.

We ask that you confirm the receipt of the order by replying to this message
that this item has been received so that we can close this claim . Please
note that we ask that you reply to this e-mail within three (3) business
days. If we do not receive a reply, we will assume the issue is resolved and
your claim will be closed.

可是我去看電子信箱裡面一封聯想寄來的信都沒有,垃圾郵件也沒有
請問我接下來該如何做呢??
我希望能收到我買的東西,真的不行至少能夠退錢給我
