Termination without prior notice and severance

I was terminated on 10th March 2023 without any kind of prior notice or feedback on ground of poor performance. I have been consistently delivering on my assignment and was confirmed on 25th Jan 2023. The project I was working on ended and after a couple of days later I was informed that I was being terminated on basis of poor performance. Also HR is telling me that I will not be getting 2 months salary in absence of notice and leave encashment as well. But joining letter states exit condition as 2 months notice by employee or employer or salary in absence of notice Kindly advise legal recourse regarding this
