Amul / Gcmmf — Selling prices of products 15% higher than mrp

Address:	827001
Website:	AMUL

Today i bought two packets of amul masti dahi (400g poly pack) which are priced at mrp rs 25/- each, from shyam stores, shopping centre, co-operative colony, bokaro steel city, bokaro jharkhand. I was quite aghast when the shopkeeper charged me at rs 28/- per packet instead of the printed mrp of rs 25/- per packet. When i asked why is it so that the selling price is more than the mrp, he informed that they get the amul products (Largely milk and curd) at prices higher than mrp (At least +1 rs). So they have no choice but to sell it at higher prices.
Request you to immediately investigate into this stark violation of consumer rights. Please let me know the action taken immediately before i take on other resort.
