Company not pay fnf

Hi i'm Mahesh Kumar & worked with Aashi Glass Ltd ,Delhi as MIS Executive around 7 Years (07 Feb, 2011 to 30 Nov, 2017), I have got a new job offer, my notice period of 3 month. I have asked my management for an early release but they are insisting that I serve full notice period. I'm belong to middle class family & lot's of responsibility. I'm left the company without serving notice period & ready to pay any deduction - 3 Months New company pressure me join as soon as possible.Otherwise, someone else will join. I don't want to loose good opportunity. Now company told me that you have not eligible anything (one Month hold Salary, 6.10 Yrs Gratuity, and 82 + Paid Leave & etc.) from this Company. Mention in appointment letter "3 months notice in writing or payment in lieu thereof" One year ago I had given the resignation in the company, and serve more than one month's notice period but Management told me we have increase your salary next appraisal as discussed and you will be withdrawal your resignation. After one year i was received appraisal letter and found my salary is not increase as discussed with management. I talked with the management, Management has denied me & said next year we will fulfill your all demand. I did not understand what to do, Management spoiled me a year, So I thought that I am doing other jobs, then i'm searching new job and one day i found the best opportunity and i don't want to loose. I'm left the company without serving notice period. i'm clear mention in resignation that i' not able to continue from today. please suggest, what can i do.
