Company Didn't settle my FNF dues

On 2000 I started working with a company Franchise Development Consulting India. From the time of covid company was paying me half salary which I was ok with. Now on letter months probably on November 2020 They fired me showing my performance issue. That is ok for me as they as a company can do whatever they want. initially it was discussed upon accepting my resignation & handover process they will clear my all dues which include 1 full month salary & half of the salary of previous month which comes a value of near about 1.66 lacs. But they will give this amount on installments .After some argument I was agreed to that also . But later they started calming that I intentionally talked with their other employee due to which one of their employee leave the job . I have relevant proof of that particular employee call recording with which prove otherwise. So this time I started refusing to accept heir terms. My uncle(father friend ) who is by chance a income tax officer got involved & try to talk to my superior for releasing the amounts but from their company started calming that I tried to influence the company officials. after this company wanted me to sign a informatory agreement which indirectly says that I accept all the allegation they bring against me. I try to negotiate with them for these agreement also by ask them to change certain points but they refused to do & this case was pending since then. Now later on I got know this FDC india against which all my offer & appointment letter ware used is not register with MCA & its just a proprietary farm. Actual company against which all my franchise signup ware done its teacreme foodworks pvt ltd & its register with MCA. One of the director of teacreme & main director of FDC india is same person Mr Saad Hannan & he was my immediate superior . I didn't take any action on this case since last 1 year . So wanted to know is there anything can be done legally.
