Termination of employment contract during probation

Dear Rajasree,

Good afternoon.

I hope this question finds you well.

I got terminated yesterday from my working place without reason, after 5 months. My contract said that they must give me a notice of 7 days.

The only answer which I got from the HR is " Manager personal reasons". What should I do in this situation, and what are my legal rights in this case?

Thanks,

Olga
