I recently bought a product from boat india and the product was defective twice and exchanged and asked for refund

When i asked for refund they are saying according to company policy we dont have refund.but according to the consumer protection act 2019 If i received a defective product after exchange then i am liable for refund but when i ask them through X they say its our company policy and when i called them they are saying sir we dont have policy to refund and when i say about consumer act they say we can’t hear you and all and i asked to connect to higher person but he said we dont have that option.he just say we dont have policy and nothing other and there customer support is the worst
