Star Bazaar — Displayed discount not coming in Bill

Address:

Star Bazaar,ISRO Layout,Bangalore

We are facing issues in Star Bazaar, ISRO Layout bangalore, majority of the time, Discount displayed near the products are not charged in the bill, there will be mismatch and we have noticed almost 2 to 3 times and have complained to the manager in charge also but they always say it will be rectified but same is repeating.

When a customer purchase product more than 20 items, we cant check each item whether correctly billed, today also faced same issue.
ex -Mammy pocko on display it was 824 Rs but in Bill it came as 899 Rs, after speaking to manager got refund but as said every time all customer will not look into the bill of each product, hence strict action to be taken on the same.
