Amul / Gcmmf — Amul Gold Milk / Madhav Dairy Faridabad

We've purchased two litre packing milk today from Madhav Dairy, Bharat colony, Faridabad but this milk curdling when it's hot and it's expiry date use before 2.08.2021 and batch no B:BF56 09:32. I said to him today is last date to use this packing milk you give me another packing but he told me that this is company packing date. We've already face the same problem many times before today. So I request you to please randomly checking at Madhav Dairy or you need to improve the milk quality. We've noticed many times that Madhav Dairy owner or persons always gives last date expiry packing milk, so please take the action against him and improve of your milk quality. Your quick and positive response is highly appreciated.
Thanks
