Reliance Trends — charge for paper bag

I hv purchased clothes on 26.1.19 from reliance trends, situated at bestech mall, mohali.. They charged me rs. 5/- for paper bags. When i objected the counter boy told me go and contact customer care department of the store.
When i contacted the customer care executive and manager they both told me our company has given us clear instructions to charge for the same. When i told them about recent case of lifestyle store which was published in newspapers on 5.1.19 in which lifestyle had been been fined for same thing, after listening to this they both says we don't care about such cases. If you wish you can also go and file case against us. Our managment says we don't care about such cases.
Daily many people objects for same thing but we don't care for such cases.
This is something against the decisions of the court and such company must be punished who do not care about the decisions of the respected court.
