Milk — charging more than printed mrp

Address:

Thane, Maharashtra

I am a resident of hiranandani estae thane, and even here the shop keepers charge us 29-30rs per liter for cow milk, and even my vendor who delivers the milk home is charging me 30 rs and hes the only person who gives this service in our building, i just fail to understand why are they charging more than whatever mrp is printed on the packet, and the consumers are least bothered to raise voice against such action.

pls i request to take action against this immediately.
