Took money showing false property documents.

Hi, OS/0100406/2023 I have paid 7.5 lakhs to a person named Pradeep KK ( Managing partner of PMR properties, Irinjalakuda, Kerala) in April 2022. He showed a plot of 50 cents out of which i was paying only 4.5 cents. He agreed to sale the plot plus a newly constructed house of 900 sq. ft in it for 28 lakhs. I paid 7.5 lakhs and rest will be home loan. We signed a sale agreement as per which the construction should be completed and handed over to me within 6 months. However, he failed to do so and he asked to renew the sale agreement, which he renewed 2 twice, for which he told that the delay is from bank and not from his side. Finally after some months i told him we don't wanted the house as there has been delays and trust issues and even he failed to show the original documents of the plot for registration. Hence, we went ahead and failed a case. Before filing the case, we even tried to settle it through police station, but he agreed a date for settlement and he failed that too. Now, he has been delaying the case without submitting the vakalath and bribing officials. I have been staying in a rented house and struggling to survive with my old parents. Could someone advice me for a quick solution or procedure to settle the case as soon as possible,
