Amul / Gcmmf — Area distributer are trying to blackmail

I am owner of tgb cafe and bakery (Naranpura, Ahmedabad, gujrat).i am purchasing amul items from last 6-7 months.
But now area manager mr.dhruv (mo - [protected]) and distributer laxmi enterprise ( [protected]) they are saying that we will not supply any product to you and we will make sure that other distributers will also do same.no one is coming to shop for order and if we call them for order they denied to accept it.
I have to purchase around 5000 per week because of this blackmailing i have to travel 3-4 km to purchase from other distributers every week.
Please make some solution.
