Big Bazaar — collecting carry bag charges

Address:

Guntur, Andhra Pradesh, 522007

I purchased for 1369rupees. I forgot bag go carry all those things and they charged me for bag 19 rupees. Is that fare?. I asked them and they said it is chargeable. I asked again that i purchased for almost 1300+, why don't you give it to me. They said chargeable. What can i do sir. Normal people also suffering for this issue. Sometimes we forget and go there for shopping. Government said that don't collect parking charges but they collecting for that also. I am just mentioning.

Please help me to punish big bazaar and give my money back sir.
