Samsung — Refrigerator defective product delivered

I have ordered refrigerator from samsung shop app on 22nd sept the fridge was delivered to me in defective condition. I raised a complaint on that same day then the company said that the defective part would be replaced but as i was worried about the condition i said i want complete replacement of the fridge then after 3 days they mailed me that they do not have any another peice so they will give me refund once they pick up my product. Then after fighting with the company for 6 days my fridge was picked up on 28th sept 2021 but still no any refund has been initiated from them and they are saying that i need to wait hut they are not sure when will i get the money. I want my money as soon as possible
