Max Lifestyle International PVT Ltd - Charged for carry bags

I made a purchase worth of *,***. It consisted of Rs* for carry bag alone and they harassed me by asking Rs* for children Welfare fund. Even though Rs * is small amount, they shouldn't ask in front of other customers. We cannot say no to Children WF as it creates bad impression of us towards society. About the carry bag incident , I argued that there is law that stops them from charging for carry bag, but still had no choice because I needed that carry bag. You cannot take clothes without shopping bag, it looks awful. But I still purchased the carry bag for Rs*. It makes no sense we purchase goods worth thousands and then they charge us for carry bag. I need justice.
