Hello (相手の名前)
I'm sorry for surprising you texting all of a sudden.
Actually, since (名前) went to Italy on his business trip, I cannot contact with him.
He said this business trip would be only three days; nevertheless, no reply comes to my text, although we were supposed to talk on the phone during his staying in Italy.
I don't even know whether he's still in Italy or he's already back.
I don't mind if he's too busy to reply me, but since he seemed very busy, I'm just worried whether something wrong is going on with him.
I heard you are the only person speaking English in your family, I mean, you are the only person I can rely on now.
I'm really sorry for bothering you, but if you have any information about him, please let me know.
Thank you for your time, I appreciate hearing from you soon.
Best regards,
(あなたの名前)
ところどころ意味の通りやすいように変えましたが、おそらくこれであなたの言わんとすることは正しく伝わるかと思います。
