[Resolved]  Reliance Fresh, Chander Lok, Pitampura, Delhi — prices listed not matching with the prices in the system

I am a resident of Delhi, I visited today at Reliance Fresh, Chander Lok outlet in Pitampura, sugar loose was listed at Rs 36.50 , when the billing was done it was Rs 37.50. Everytime I have to argue with the staff for the same thing. For Rice[Kohinoor] they have put up Buy 1 Get 1 free, ,at the time of billing counter salesman is telling that the scheme is over or it is not coming in their system.
This is basically a fraud what reliance is doing.
If by mistake I do not ask whether the item is under scheme or not, they will bill the same and at the time of payment if I tell them I dont need it now, then they are not even ready to help, they would say it cannot be cancelled as they become answerable , why the bill was cancelled.

It is a pure case of cheating

Is there anyone who has a reply to my problem or should I approach Consumer Court
