Termination shown as resignation, done salary adv recovery from my FnF settlement

I have been terminated in an internal proceedings of a sexual harassment against me by a company employee, wrongfully, my stand and witness did not taken into serious consideration and in final report, the IC shared my employer to terminate, while my employer did not terminated me, instead he forced me to write resignation due to personal reasons with immediate effect, and then, my leave encashment amount and my yearly professional merit scheme earnings all deducted under salary adv recovery without my prior permission of prior discussion or even without informing me of such deduction will be done on my last day of working, and I have not been paid off any amount of my earnings of the same by the company. they are also saying they will not provide me relieving latter from the employment as well. The IC proceedings happened totally on a biased approach towards the girl who filed the complaint with many wrong allegations on me but still she had been saved by the all IC members, even the external member of the IC did not pursue neutral approach and stood on the girls side, even though I had substantial arguments and proofs of her false claims. I have been harrassed mentally and emotionally, due to the girl, my marriage is about to end yet only I have been on the side of blaming and injustice by the company and getting troubled. what should I do in this matter as I have no clue how to deal with the MNC giant's one sided actions. I have given 9 yrs of my service to the company.
