The way you have been terminated is illegal. You can challenge such illegal termination in the court of law. Depending on your nature of duties, it can be decided whether you will fall under the category of workman or not under the ID Act. If you challenge the termination, then you will be entitled to reinstatement and back wages. But in your case, since you have tendered resignation (although on advice of the management), you have to immediately send a letter asking such resignation to be treated as withdrawn unless you have proof that such resignation was obtained from you forcefully.
But if you do not want to challenge the termination, but remain satisfied with dues and full and final settlement, then depending on the nature of your duties, nature of the company with strength, your tenure of service and the amount of last drawn wages, you can get your outstanding dues.
Please note that you cannot challenge the termination of service and F&F settlement at the same time. Only if you accept the termination, you will be able to ask for F&F settlement.
