Vishal Mega Mart — Extra payment charged

I am a regular customer of Vishal mega Mart this never happened before. As due to covid-19 we all are avoiding crowd so I could not check the bill instantly. Today I observed that one of the item of the list were added as 2 item, as I bought 1 curtains but I have charged for 2 there. Thus I have paid extra Rs. 300/- and even one item was also missing of Rs. 60/- from the list . I don't understand what type of checking those people are doing on the exist. If something extra apart from the bill is added mistakenly in the trolly bag than they back fire the customer, so its there equal duty to make the customer aware of there missing item as well, it works both way right .
