今日荷物が届きましたが中身が違っており999が届いてしまいました。至急888を送ってもらえますか？999はすぐに返送します。返送料は後ほどPayPalで請求する形で良いですか？
I received the package today, but with wrong contents, i.e. 999 was contained. Please immediately ship me 888. I will return 999 to you promptly. I will invoice you the return shipping fee to you via Paypal, is it OK for you?
