Regarding my full and final settlement

Hello, I was working at Call it Spring store under major brands at mall of India, Noida. I had resigned on 04/05/2017 and serve my one month notice period till 05/06/2017. As per company policy my FNF have to release after 45 days but due to my attendance regulations I was not get it on time. So,I contacted to HR he said that you need to prepare a excel sheet and mention your all days availability on floor including your casual leaves and take approval from your store manager so I did that and got approval for that too but after three months of my resignation they credited 3280rs only in my account. So, I again talk to HR and I told him that as per my excel sheet and floor availability it was total 42 days and you suppose to credit the amount for 42 days. So, HR took 4 months again for release my FNF and then after he credited 7511rs only last month which suppose to be 19000 approximately. My monthly salary was 1735rs per month over there. And now no one response my call over. Now it is about the money, it is about my right. Please any one help me what to do and how I can get my money from them.
