Want my 4 lakhs of rupees back from property dealer

Last month I planned to buy a property to make it godawn. So property dealers in my area showed us area which they cut from the parking space in the ground floor and told us it is totally legal to built a godawn here and a small office. They got me tricked and I paid 4lakhs in advance as token money, but on the second day we got to know that it's illegal to use parking space as a commercial and it will be sealed if govt. Got to know about the same. So I decided not to buy that and asked dealer to give me my money back. He said your money will be safe with me and you are planning to buy so I will show you more properties...but after seeing too many properties and ol now I don't want to buy property as I need those money to invest in my other business and will buy property after some time. When I told this to property dealer he straight forwardly said that your money is now finished do whatever you want we are not going to give back your money. You can either buy new property and we will cut the 4 fr that amount else it's gone Now my 4 lakhs is stuck with this property dealer and I don't know how to get it back I don't want to invest more in proeprty as I m afraid that my money will not be coming back Please help me
