Deducted prp and bonus - whether i am eligible for my bonus, prp and earned leaves or not?

Hello Ma'am/Sir. I have joined a company in India on 1st July 2018, they gave me an appointment letter and Annexure with a package of 6 lakhs per annum. After 5 months of joining they changed the CTC structure and provide us a letter about change in structure, according to the new Annexure, Bonus @8.33% of Gross Salary, Performance-related Pay (PRP) @10% of Gross Salary, and PF (Employee's and Employer's Contribution both) will be deducted from the current package of 6 lakhs from 1st dec 2018, and it was assured that you will get the deducted amount after completion of one year and called it SAVINGS. According to the appointment, I've completed one year on July 1st, 2019. But I did not receive any communication or information regarding PRP. As I resigned on 19th October and asked for my settlement including Bonus and PRP, company claimed that I am not eligible for Bonus and PRP as it's not a complete one year of deduction of that amount, but according to my joining, I have completed 1 year of service in July 2019 itself. Secondly, after completion of one year, I earned 7.5 EL for the rest of the calendar year, but they are not paying for that also, as according to them I am not liable for this before January. So, please look into it and tell me whether I am eligible for my Bonus, PRP and earned leaves or not. And if yes, please suggest me what should I do to get my money.
