Hi i have purchased Rajbhog Ice cream of 750ml. But when i opened it then saw the real ice cream not enough it was happened first time with me, i always preferred amul but this is really bad experience i ever had. According to me out of 750ml i had only 400ml in the pack. Why this is so? How do we verify weight before purchasing? This is not good for amul. I want solution.
