Schengen visa (for work) to Hungary still not received.

Applied through Kolkata VFS on 11/2 and application reached Hungary Embassy New Delhi on 13/2. Till then from today, it's processing. I have my flight this Saturday (28/2). This is for official purpose that I will be travelling. My coworker applied from Delhi and got the visa within 5 days. I am so stressed and worried now because I think I'm going to miss this opportunity of travelling to the client site. Had a lot of dreams and planings . Mailed the embassy many times. Seems like nothing will work. I'm really disheartened now! I really wanted this change because life has been really hard for me lately. Seems like there's no way out.
