前金に応じてもらえないなら、あなた方に早急に日本の倉庫へ来てもらって私達と現状を確認してもらって、その場で返金してもらうか、返品になった分を全て引き取って返金してもらうか、どちらかで対応してもらえますか?
If you are not to accept the advance payment, we would like you to either immediately come to the warehouse in Japan and refund at site after checking the circumstances with us, or to receive all returned products and refund. Will it be possible for you to choose one of these options?
