Consumer Redressal

Dear Sir, Please give us advice. We have delivered the material to the local transporter, He refused to give us any receipt/bill against that material, now 10 days later he didn't despatched to our client. The material is retained in his godown, even he is not telling us how much freight charges we have to pay, and when he will delivered the material and refused to return the material. How can I claim the material, compensation and lodge the police complaint against him.
