Amul Cream Milk — not getting full cream milk.

I m living in colaba badhwar park mumbai. I visited so many distributor for amul full cream milk and asking about amul cream milk to the distributor. But i m not getting the cream milk. They are unable to supply as per my required demand. On some occasions may be once in a month, i m getting it but the distributor demanding more money near about rs.7 to 8 than the mrp. Request take necessary action, so that i get the cream milk.
