Fraudulent Renovation Contract and Non-Responsive Local Police Station

We hired a contract for a renovation project, who took a substantial sum of money (INR 6 lakhs) and has not fulfilled his contractual obligations. Not only did he leave the project incomplete, but he has also failed to respond to our repeated attempts to reach him and resolve this matter. After facing repeated delays, we approached our local police station to file a written complaint against him. Unfortunately, despite our persistence, the police have not yet filed a formal complaint. Instead, they keep suggesting that we go to the consumer forum and refuse to take proactive steps to contact or apprehend the contractor. It appears there may be some bias, as they even questioned whether we consulted them prior to signing the contract, which we feel is an unfair response when seeking protection against a clear case of fraud. We have been struggling with this issue for over a month and feel we have exhausted the usual channels without any resolution. We want our money back and want police to investigate. Please suggest the course of action as I don't want the actions to go unchecked and people like him take advantage make people like us suffer.
