Instead of communicating through email you may resort to making a proper representation in writing sent by registered post to the top management expressing your grievances and sorrows due to sudden and unjustified termination of the employment besides you can demand the settlement of F&F and other dues from the company side which are yet to be settled.
If you don't get a positive response or the company is not entertaining your claim you may resort to legal action by first issuing a legal notice demanding the your dues and also to reinstate you in the company.
After that you can decide to file a writ petition before high court seeking relief and remedy.
