Visakha Dairy — Milk

Our family is u sing visakha milk product since 23years but have never gone through this defect in the product which we have been seeing recently. The problem is the milk tastes so powdered milk and also after skimming the milk to curd the actual damage arises, the curd which we use from the visakha dairy milk packets is so strange that it is actually becomes as jelly part when we serve it .our curd recently is so saggy and very different from a general curd structure. Please look into our problem and the production of the milk.
We actually use visakha diary milk packets which is red in colour
