Amul / Gcmmf — Charged more than MRP for Milk

All the shopkeepers in Jogeshwari East - 400060 Mumbai are charging customers Rs 1 per 1/2 liter more than the MRP printed on the package.

When asked why they are charging more than MRP, they said it is the cooling charge for keeping the milk fresh.
For 1 liter of milk I was charged Rs 54/- instead of Rs 52/-

Please find the attached bill as evidence where Rs 52 is charged for milk and Rs 2 is charged as cooling charge.
