As others have correctly mentioned, Jet Airways is very poor when it comes to paying compensation. I'm still waiting over 9 weeks for a flight delay compensation covered under EC261. The only way to get them to respond is to email guestrelations@jetairways.com.

I wouldn't hold your breath for compensation. Since you mention corporate travel, have you checked if you're covered under your corporate travel insurance ? It maybe quicker to claim via them. Also, you can check your corporate travel policy for such cases, some companies cover such costs as well.
