D-Mart / Avenue Supermarts — Had taken pack of twelve tetra packets Amul milk from dmart

I had taken twelve packets of Amul tetra packs from DMart on 15th August. It has a six months expiry. When I opened it two packets were spoiled. On calling them they said to send pictures and also to keep the packets which I did but since it’s spoiled milk next day my house started stinking I called them again to give a resolution as my house is stinking to which they said they will get me a resolution again I called in the evening as the smell was unbearable. They told me first to keep the two spoiled packets out of my door on telling them I will give it to DMart ready opposite my house let them keep it as much as they want and you can give me a resolution I was put on hold the second time and after some time I was told to go to Amul and raise a complaint for the two spoiled open packets and the rest intact packets to return it and I will get a refund.
This is not fare I have taken the thing from DMart they should take the product back and refund me the money.
