連絡有難うございます。やはりそうですよね。
Aを購入した彼は並行輸入品だと知らずに購入したそうで、保証がきかないことが分かり怒っています。私の方で何とか対応します。
ただBの方については試用段階での故障ですので交換をお願いします。
Thank you for contacting me. It's just as you thought.
It seems that he purchased A without realizing it was a parallel import good, and is angry to know that the guarantee won't be carried out. I will deal with it somehow on my end.
But, as for B, because of the failure in the trial stage I'd like to do an exchange.
