Nilgiris Super Market. — quoted high prices than mentioned and mrp prices

Hi, today we have purchased some groceries from one of your Nilgiris store in banglore, this is not the 1st tym we are purchasing but this is the 1st time that we have checked your computerised bill, after checking this bill we came to know that there are some mistakes in the bill, like MRP rs.11/- masala Maggi noodles priced in the bill as MRP rs.11.64/- and kilo Mango Banginpally mentioned in your store as 59.90/- and in the bill it is priced as 64/-, you people are literally looting our hard core money...I want to complain this to the next level, I have all the proofs.
