Improper investigation under 156(3) by police and judge dismissing the application

I filed criminal complaint under 156(3). One set of charges were under section 403 and 405 for the patented moulds (my assets) entrusted to the accused as a collateral for performance security which were to be released after completion of project. The project got completed and client raised no complaint regarding work but refused to return moulds in spite of several reminders. Another set of charges were under section 418 and 420. The accused promised in the work order that work contract tax shall be paid by him on my behalf as rates were decided exclusive of work contract tax. He promised to issue me certificates of payment which can be deposited by me to tax authorities to claim exemption. However, he failed to give certificates as he fraudulently filed nil return to tax authorities even though as a subcontractor I filed tax returns showing the turnover of the work done with him. Thus, I was forced to pay tax along with interest and penalties. Even, I collected proofs of nil returns from tax authorities through RTI. However, police just took a written reply from the accused who just asserted that he had already returned the moulds and he filed nil returns as he did not do any work in those years. He did not attached any proof of his assertions. The police told the judge that matter is of civil nature and is devoid of any criminality. The judge dismissed the application filed under 156(3) as he asserted that there is no need for investigation as the facts of the complaint and the identity of accused is known to the complainant and matter is related principally with breach of contract. He asked me to render evidence at pre-summon stage under section 200. I feel that judge is trying to weaken my case and will later reject it under section 203. I feel that I should appeal that my complaint should be again investigated under section 156(3) as I feel that investigation has not been properly done. Police can find further evidence against misuse of moulds and evasion of tax if investigation is properly done. How should I proceed?
