Swiggy — Charging more than the bill amount

I was charged extra on bill {order no.[protected] }. When i reached out to a representative she tried to lie to me telling that this amount is for dine-in, when i told her that swiggy is clearly mentioned on the bill she jus closed the chat. A customer has to pay the amount that is mentioned in the bill, if there were any additional charges they should have been mentioned before placing the order. By not returning the extra money swiggy is doing shady business and looting people. Moreover the support team on the email is also in on this scheme of looting people. Imagine if the cheat people of 10 rupees per order and they process 10 lakh orders per day. they have earned 1 crore just by cheating people.
