Mone back

I have consulted a property dealer for buying a plot on 30th November 2017. I have paid all the money that he has instructed me to pay first.... 11000 for token money and 39000 cash, then he gave me the time till 25th feb 2018 to get the housing loan sanctioned by bank but because of my credit score was not up to the mark to get a loan of 30 lakhs, my loan requisition was getting rejected from everywhere. This I have informed him within 10 days. Then said that '' Don't worry I'll make your loan sanctioned from somewhere else" and he was charging double the interest rate from market. So I denied his offer and asked to return my money. He said that okay come after a week and take your money back...from that time till now he is postponing the date and also when I am talking to him on phone he issl threatening me and when I visited his office yesterday surprisingly, he was threatening me there also. It is clearly mentioned in his receipt that If i am unable to buy the plot he will return the money but now he is not returning. I have all the documents and proof. So please help, 50000 is really a big amount for me.
