確かに、「修復品でも動作に問題がなければ良い」ということは理解できます。
しかし、これは日本人特有の考え方かもしれませんが、一度問題が生じた商品は使いたくない、という「心情」があるため、新品と交換ではなく修復品を再度送る、というあなたの提案を了承することはできません。
どうか理解してください。
But we Japanese feel that we don't want to use the item to which some problems happen once.
It may be special feeling for Japanese, but because of that, we can't agree your suggestion that you would send the repared items again instead of the new items.
Thank you for your understanding.
However, this might be a unique Japanese idea, but I have a mind that I do not want to use the item which have problems once, so I cannot accept your offer of sending me back the repaired one instead a brand new.
Please understand.
