Court dismissed cheque bounce complaint in recovery case. What to do?

I have given the loan to some other company against his shares of the equal amount also i have received the cheques of the same amount of loan. After the expiry of period, the other company has not paid the loan amount so in terms of the agreement we have sold the shares but the value of shares was decreased and total amount of loan's only 10% recovered. THen we also presented the cheques before the banks but they also dishonoured. On filing the complaint before the court the court has dismissed our complaint on the ground that you have realised your amount of loan by selling the shares and thus, dishounouring of cheques does not fall under the purview of 138 of NI Act.
