Panchwati Restorent/ Dhaba, Jagatpur, Raibareli — Charging money more than mrp & not giving bills.

Sir i want to seek your attention for this topic. A restorent/ dhaba named panchvati on lucknow - allahabad highway is charging more than mrp of products. At the same time they are not giving proper bills for edible goods. When people ask about same they start misbehaving with the customers. This restorent is located between jagatpur & raibareli. I seek needful action to discourage such practices. Thanking you!
