Shall i relive in 1 month but the notice period is two month

If the notice period of 2 months is mentioned then you have to serve 2 months. Try to amicable settle the issue with them.

they are saying to complete the task which take more the 6 months in two months and they are saying me they will claim the case on me .

so it will affect my career.

so pls give me a solution how to come out of company without any issue in one month.
