Windeals — about a contest prize

Address:	Pune, Maharashtra
Website:	windeals.in

On day i got a call from windeals.com. He told me " you have selected for tour prize. For that u have to buy one product from us. Due to continue getting call for the same then i bought one product of ₹450. After that he told me u have selected for switzerland tour. And i denied then he said okay no problem u can take money instead of tour package then i said ok. Again i got one call. Then he said u have to pay ₹6500 then u can claim ur prize amount. And i paid. Then after few days company again said to me you have to pay ₹18000 for gst amount. But on prize individual has to pay income tax not gst. Gst is charged only for goods and
Services. So that time i realized this is a fraud company. Now i am demanding my money back but they are not picking up the call... What can i do please help us. Government should take action on such fraud company.
