Fraud by real estate marketing partner

Hi All, I have been contact by real estate marketing partner. who had complete property document of few plot. out of which we negotiated and said yes to one of the plot. We got documents legally clarified and we made a mistake of making payment of 30% to marketing partner name. He assured us he will arrange for Sale agreement within 1 week. But later got to know land owner didn't receive the funds from him. So when cross checked with him. He mentioned he used that amount of other project and buying some time from us. We got cheque from that amount and it got bounced. I have already filled cheque bounce case now under section 138 in migestrate court. Where we can recover actual amount after some years. still court order is pending. But i want to file consumer case against him with compensation for the damages done . ( Interest of 10 L amount + loss of opportunity + mental agony, and harassment ) How can i proceed , can you please guide me ? Should i wait for Court order or payment back from opposite party on cheque bounce case and then later file consumer court case on him ? Please let me know on this. Regards Uday
