Verbally terminated - Hr Terminated me without notice period without any written letter

Hello All Kindly suggest me. My company XXX.com Noida. Hr Terminated me without notice period without any written letter.
What should I do?

What is the nature of your job?
If you were a person employed in the category of workman, you can raise a dispute u/s 2-A(1) of the Industrial Disputes Act,1947 before the ALC for the area where you worked last before such termination claiming reinstatement and back wages with continuity of service.
If you were employed in any other higher category, you may institute a Civil Suit claiming damages for wrongful termination by way of breach of contract of employment.
However, prior to any one of such legal action, send a notice to the Company stating that the act is illegal as it is violative of the contract of employment and as such if not suitably rectified forth with, it would entail in seeking legal remedy from your side.
