False portrayal of food offers

This complaint isn't regarding a specific order from the app but the overall representation of offers on food items like for example during the festival time the app showcases food items like Biryani for rupees 39 but when you actually finalise the order the total order bill goes up to 127 nearly multiplying by almost 2.5 Times which is a small scam to be honest and the bill breakdown shows the delivery to be 66 double the actual amount shown in the offer and other delivery tip is also added which is unfair I am not against the total bill price but the overall representation of a very low amount but it actually sums up to actually greater amount so this gives a false portrayal of offers and place severely on the consumer low price psychology which is illegal
