Check bounce case

Dear Sir, Two years back I filed check bounce case against Unitech builder .They refunded money after 7 years of non construction and out of 7 three checks bounced .cross exam stage of complainant is over .Unitech lawyer is trying his best to mislead the court that I should approach Amicus Curiae for grievance against builder .my lawyer told Judge since I entered MOU with Unitech I m no longer buyer .In MOU unitech wrote if any check fails to be honoured I am free to file case against them . On Next date Unitech Lawyer will make statement .When my lawyer said next accused will be crossed Unitech lawyer mocked n said our lawyer doesnt know law accused cant be cross examined . I want to know how to recover money . Checks r signed by Chairman Unitech and MD unitech ,n they have accepted their signs. Should I file civil suit ,should I go to amicus curaie , should I go to higher court .They r very powerful MD is enjoying in Tihar and Father Chairman is outside but giving medical cert seeking waiver . How to get money back . Amicus Curiae had last year in HT said all buyers should for inform him including those who have MOU .Although I have MOU ,as per my lawyer I am not buyer I did send details to amicus . In HT newspaper there was no mention that amicus will solve check bounce case. Does informing amicus finish 138 case.
