You have stated that you are employed in a reputed company. Then the compnay should have framed procedures of suspension, subsistence allowance payable, procedure for imposing punishments, etc. Hence, it is necessary that you have to go through the standing orders/rules/regulations carefully and seek redressal from the company under the said rules.
It is not known the status of your employment with your company. Are you a workman or a supervisory staff in terms of teh Industrial Disputes Act. If you are a workman under ID Act, you can prefer a complaint to the jurisdictional labour authorities. The labour authorities will treat it as a dispute and initiate conciliatory proceedings. The Labour authority has power to summon the Company authorities. If no reconciliation happens at the Labour Authority forum, the matter would be referred to the Labour Court.
You may seek assistance of any labour lawyer near your place.
If you are a supervisory staff, you have no recourse to labour court. Then your position will be in relation to the contract of employment. You have to file a writ petition with the Court.
Unless otherwise mentioned in the contract of employment regarding jurisdiction of the court, the case has to be filed at the jurisdictional court where cause of action has arisen. Since you were terminated from the service at the last place of your posting, the case has to be filed at the jurisdictional court. You may engage a lawyer to present your case. Your personal presence is not necessary always. You can follow up with your lawyer. Only at the stage of evidence, your personal presence may be necessary.
So, please find a labour lawyer and proceed.
Wish you all the best.
