Morestore — Incorrect bill on Dove Serum Bar doap

Today I purchased Dove serum bar from More Retail Private Limited Sripuram Colony Moosarambagh Malakpet Hyderabad 500036. The unit price is ₹249 on Dove pack of 3bars whereas the unit price shown on the bill is ₹270 & shown a discount of ₹23 & total price as ₹247. No where on the Dove pack unit price of ₹270 is written & looking at the actual discount is only ₹2.
It's clear act of cheating the customer by not updating the unit price in system & giving only a discount of ₹2. The bill is incorrect, hence I request to take necessary action against the store for cheating the customer in the name of not updating the price in system. I request to do the needful in this regard for refund too as penalty for cheating.
