Employer not releasing my pending salary

I am struggling to get my due salary from my employer from last 5 month . I have been hired from X employer and was on payroll of Y employer. My Y employer is located in Bangaluru and X is located in Noida. I worked in Noida in the premises of X branch. My last working day was 20th Oct'17 after serving the 1 month notice. Since then I have waited for 45 days for F&F settlement. After several reminder and followups I got my relieving letter on 21st Dec'17 however there is no salary credited to my account. When I asked for the reason my Y employer gave me several reason on every follow up like : 1. Approval not received from X employer 2. There is no amount to be credited as per their rule of 80% +20 % salary structure (quarterly) 3. Person is not available at X employer and Y dont know about the calculation .. this has to be clear from X employer. On 1st Jan'2018 I received a mail from my Y employer that as per the calculation I have to return them 2.5K rupees after all the deduction when I asked for the reason and calculation they routed me to X employer. I asked the X employer about the calculation and they responded me its a correct calculation as per the pro data base. I calculated every thing on my own and submitted my calculation to the X employer which was 7K rupees they have to pay to me. After few days wait they told me that my calculation was right and they have asked the Y employer to release my pending amount. In the 1st week of Feb'18 I follow up with the Y employer and they assured me that I will get the salary in this present month salary. Today on 1st Mar'18 I contacted the Y employer that I have not received the salary and surprisingly I got to know they are trying to understand the calculation from X employer as why Y employer has to pay to employee. I am in state of mind that this time everything will be fine. I am so much of pain these entire period. I did not get any job , I am unable to fulfill my financial needs. Now I dont what to do , should I quit my salary or go by legal against such stupid employer who didnt know the calculation and didnt tried to understand the calculation when I was asking the calculation. I feeling mentally harassed by both the employer , Please someone guide me or suggest what to do?
