Amul / Gcmmf — amul cow milk

Address:

New Delhi, Delhi, 110065

I buy 5 - 6 litres of amul cow milk and store it which last me 3-4 days. On storing milk fats are deposited inside layer of the polythene pack. On some days there is thick layer of milk fat and on some days there is no milk fat and seems like mother dairy milk and also the milk packet has less air in it. I have been purchasing milk from c block market, east of kailash, new delhi -110065. I feel something wrong is happening on some days. Please look into this.
