Confused About Leave Deductions at Work? Seeking Advice on Unclear Policies and Pay

Hello seniors, my query is about leave and deduction in hours at our mining company. Our management people are stating 12 leaves, i.e., 1 leave per month (but they have not mentioned the type of leave). I joined the company in November 2010. From December to May, including Sundays, I took 11 days off. They deducted 5 days from my June month's salary. I received an unpleasant response from my senior regarding this issue. They have not yet defined any type of leave structure, but they are planning to do so for the next month. If they do implement a new leave structure, can I get credited (paid leave) for the deducted days after one year?

I am working in a PSU on a contractual basis through the contractor of the PSU. How many leaves can I avail in a year? What are the rules of the central government regarding leave in my profile? Kindly respond to me quickly; it's very urgent, sir. If documents are available, please attach them with the post. Thank you.
