もちろん､荷物はデータ上､倉庫に到着していることは理解している｡
倉庫側で荷物を捜索するのに発送伝票(送り主､受け取り名､住所､追跡番号記載)を要求されているんだ｡
残っている?? もし可能なら次回のオーダー分から発送伝票を念のため残して置いてほしい｡
いつも丁寧に対応してくれて本当にありがとう｡

Of course, I understand that the package has arrived at the warehouse in the data.
They are asking me for the shipping slip (sender, recipient name, address, tracking number) to search for the package at the warehouse.
Do you have it? If possible, I would like you to keep the shipping slip for the next order just in case.
Thank you very much for always being so polite and helpful.
