No broker buyers plan - Denied my refund

I choose a premium buys plan to buy a property. And I finalised the property and made a payment of ***** as part of subscription and ***** as token advance.
Later I got to know the property was **years old where as the nobroker agent and seller lied that the property was **-** years old. I was completely not ok with proceeding with such an old property with extremely high price. I contacted the relationship manager from no broker they never picked my calls. And not ready to refund the amount. It’s been more than * months and yet no updates
