Refund of My advance amount

Good day everyone, On jan 2023, i went to see one residential property. I was interested in that property as seller wanted to sell it off very fast too The quoted price was 65lacs. One day me and the seller discussed about that property and seller told that it's valuation is more than 70lacs, so as I would be taking loan so i accepted the seller offer and the very next day started the loan process. The seller told that the sale deed will be of 32lacs So i need to pay 10%of the sale deed amount to get the loan sanctioned and i paid that amount which is 3.2 lac When the loan process was completed the valuation of that property came as 59lacs and the loan amount passed was between 48-50lacs. And i was shortage of 10lacs. I asked seller to give me some time as ur property valuation ame less and loan amount passed also less. But seller denied then i asked seller to cancel the deal and refund my advance amount of 3.2lacs. But seller denied to refund my advance amount saying this will not be refunded bcz i cancelled the deal. Please advise me , how i will get my refund As proof i have sellers bank statement and mine bank statement too
