Regarding fraud in e stamp

Sir, a firm called me for a job offer ,i didn't knew that it was a fraud, they made me sign a non judicial paper on Govt of gujrat, I didn't read all the clause as they were saying that sign it or job opportunity will be lost. in the stamp paper, they made me sign on first paper under the heading "agreement" and then there were some clause about data breach, and other clause related to the job .at the end of the clauses i signed and the the first party also signed. it is after this point i suspected that it is a fraud and i didn't signed the laste page where i have sign the undertaking- undertaking said that it was my responsibility that the signed i provided digitally is true and in non-compliance of the contract i have to pay 10000. I want to ask that since i have not signed the undertaking ,Can they sue me in court for compensation?they are calling me that they file court case and apply some compensation charge of Rs20000 in addition to 10000. my point is if i have signed the undertaking/declaration the contract is not legally enforceable and they can't sue me in court for that. Please help me as they are threatening me that they go to court and downgrade my CIBIL score.
