Swiggy — overcharging customers

Hi
I have purchased the veggie sandwich from subway priced at 135(with taxes) as a parcel however Swiggy is charging the same sandwich with same ingredients for 175(excluding taxes and packing charges).
Why no one has ever contacted me regarding this. Why is swiggy overcharging their super members? Why can they not charge as per the rate which the restaurant selling price. If they are looking for profits then they need to deal with the restaurant owners not by overcharging the customers.
