Address:

Core-Value Technologies, 1617, WTT Tower, Sector-16, Noida, UP-201301, Gautam Buddh Nagar, Uttar Pradesh, 110092

Complaint is regarding swiggy, as seen in attached screenshot, when i tried ordering from "aggarwal bikaneri sweets-sector 18" i got price of 1 kg "desi ghee motichoor laddu" as 190/-, i clicked the icon to continue ordering,

On moving inside i kept the quantity as 1kg (Which itself have rs.190 specified against it, as can be seen in screenshot), but total price came out to be 380, i want to know the reason for this variation, is this just a technique to attract the customer.
