Flipkart — I want compensation with phone

My order is OD[protected]. I bought a new phone Infinix zero 5g 2023 at no cost emi from flipkart.It was an open box delivery and when delivery boy was come he open the phone box himself and take otp fast and he went immediately. When i come at my place and check my phone properly there was some scraches on phone without my touch. How it possible? I complain at flipkart but they denied because of open box delivery. But i dont have much time to check phone at the time of delivery. Now what i do? I think the phone is open for service... I felt cheated.. I just want new phone nothing else.. plz help me. They call after some days and say that they change my phone. But till now no any movement from flipkart. Now i want compensation for harassment.
