Tata Cliq - Received used product and broken sealed product

Hello Team,
I have received a used phone and it was opened sealed . I contacted tata cliq customer care they manipulated me in such a way that I got confused and later on they said I have used the product so they cannot return it .it is clearly showing in the policy if. Sealed is broken or a product is used it lies under return policy . I have been reaching out to them to return the product or even offer me a replacement but they are not doing it ..

They won't value about my money that ai have spent to bought a new phone .
