What ?
 

What do you mean by "Seikaichuu Sabisu kaisha" ? (In the world Service Company)

Thank you so very much :D

Do you mean International Service Company?

Yes, thanks it seems so
It is a company name and I am thinking if it is International, why shouldn't it be Kokusai instead of seikaichuu that sounds really odd

It's not せいかいちゅう, it's せかいじゅう. In kanji, it's 世界中, and it sounds more like "Worldwide" to me.

I think the distinction here is that 国際 would sound like "offices in different countries," while 世界中 means that they ship worldwide.

It's じゅう (throughout), not ちゅう (in/during).

Yeah, you're right. I've edited above. I don't know what I was doing.
