Cheating case

Hello Sir, This is to file a case of cheating against an agent (name Muralidhar, Anekal, Bangalore) for approval of the building plan that I am constructing for a 2 storied house in Bangalore. I had paid a total of Rs. 10,000 (Transferred through CITIBANK online transfer to his bank account - split as Rs. 7000 (on 21Mar18) and Rs. 3000 (on 21May2018)). This was the initial payment for getting the BMRDA approval done for my house. After the last transfer (of Rs. 3000/- on 21May2018 as specified above) he is not responding to my calls and no response to my whatsapp messages. He was in touch with me for the last 2 months saying that he had to change the drawings because the authority have suggested changes to the drawing etc. He even sent me the modified drawings. But suddenly he is not taking any calls. Hence I have proof that I have transferred the money into his account (CITIBANK Statements dated 21st March and 21st May 2018) and Whatsapp messages. What legal options do I have? Most importantly he has taken all my property documents (Photocopy only) with him (Sale deed copy, my ID proof, Khata, Tax Paid, Drawings etc) and I need to retrieve these documents as soon as possible. Please advice the further course of action. Thanks, Sivasubramanian.R
