paypal 退款 - 海外購物

我跟一位瑞典的賣家買東西,用paypal付款
收到後發現不是他宣稱的正品
於是上paypal申訴

賣家同意退款,但是請我寄還給他,對方已經收到商品,並在dispute上這樣回應;

We have agreed on a full-refund in the case the customer send back the shirt
and cover the shipment.

問題來了

這個賣家接著把糾紛升級成索賠,paypal馬上作出以下判定

Our investigation into your claim is complete. As stated in our User
Agreement, the claims process only applies to the shipment of goods. It
does not apply to complaints about the attributes or quality of goods
received. Therefore, we are unable to reverse this transaction or issue a
refund.

所以就結案了.......

請問接下來賣家怎麼退我錢啊?
