Swiggy - Non veg item delivered instead of veg item ordered

This complaint isn't about money loss. But it's about carelessness. It's about religion and beliefs. Swiggy delivered Omelette paratha instead of baingan ka bharta and paratha.
And when I complained they said sorry won't happen again. My point is it should not have happened in the first place.
I am asking about talking to their senior management. Rooma (their agent) is ignoring my messages and talking about refund and all. Highly disappointing. Then after I told her I can sue. She replied saying call from senior will come in an hour.
The call came but there was a junior agent on call who have nothing to say or any powers. I told her very clearly that I want to talk to some senior person. I was assured that a call will come in an hour. It's been more than * hours. Still no call. I have kept that wrong non-veg lunch there as proof. Somebody tell them it not always about money. I want to sue swiggy for this.
