送って頂いたという差額の請求書が見当たりません。どちらに送りましたか?どうも100件ぐらいのセラーとやり取りしているので、ごちゃごちゃになっている可能性があります。すみませんが、再度、請求書を送っていただけますか?またその請求書はpaypalで払えるものですよね?
重ねて申し訳ないですが、よろしくお願いします。
I cannot find an invoice where difference is listed that you had sent to me. To where did you send it? As I am communicating with about 100 sellers, it might be confused. I am sorry to ask you, but would you send the invoice to me again? I assume that I can pay the invoice by PayPal. Am I correct?
I hate to ask you several times, but appreciate your understanding in advance.
