Reliance Mart — faulty billing at reliance smart

Today i visited reliance smart store at nayapalli, bhubaneswar, odisha. I purchased 5 items and came back home. At home i found that the rates charged are higher than it was written in the counter and told by sales persons. Two items of mc cains (Potato bite and viggie finger) are billed at a discount of 10%. But it was written in the counter as 25% and the same was confirmed by the sales person. Again orange imported was told by sales people as rs.149/- per kg. But charged as rs.199/- per kg. I think there is a problem in my bill. Kindly look to this. I am attaching the bill for your reference.
