Termination with False alligation or without any pay or Experienc

Hello, I am Seeking your advice on My Job.I Should say my ex. job. I was untill yesterdayworking in a firm.HR person called me to office and said we are terminating you immediately.In Midnight I am a female employee working in night shift. Thet said they will not provide any payment and experience letter. Reason-They said i Provoke other collegues to resign.(Thing is My collegue asked me to forward Resignation format i just forward a mail which i puted in August 2015. and that collegue accepted that she aske that email from me but they terminated me and give another one a warning.) actual reason is that they come to know i am going to resign in next three days because of persnol reason and also because of mental harrasment for not doing my appraisal which is due from July. i was top performer in my company. They also pressurising me to take team lead position and when i denied and mentioned i am taking 1 year break because of persnol reason if they want to track they can. Other thing is after 3 day i was also going to receive my incentive and arrihals for past three which they promised almost 45000/- so they terminated me with false alligation to save money. they did not provide me any warning and time to put my point . Apart fro that email they dont have anything. I worked their for 2 years 10 months. They dont have any return proof about to provokeing anyone. They told me they will not give any experience letter and they will destroy my careear. They are mantaly harrasing me from three months. I need my experience letter.
