I agree to your point and am sorry about the scenario that you are into right now. Legally, your employer / company should give you a minimum of 15 days PL unless it is governed by some other exemption rule put into implementation by your company by availing the notification in official gazette. However, you should give a written application (through your superior) to the HR team requesting to consider your case as a special one mentioning facts. Generally, leave rules are quite clearly set in most of the organizations, but most of the companies consider exceptions as well. All depends upon how employee friendly your company is and your relation with your company.
Try your luck.
