Company sacking me during appraisal time without notice period

I have been working with a retail company for one year now. However, when appraisal time came, the company suddenly asked me to leave on the grounds that my performance was not good enough. They even failed to give me any notice period.
Please suggest what options I have to safeguard my interest.

Dear Shweta,
Pl go thru the terms & conditions of your appointment letter which will help you in understanding the company policies & give you idea about whether pre-appraisal is possible and also about your notice period pay.
