Swiggy — non veg thali delivered instead of veg thali

Address: New Delhi, Delhi, 110017

I am a pure vegetarian. Had ordered a veg thali today, and was given a chicken thali. I realized that when i started eating. As when i conveyed the complain their representative they told me they cannot refund the amount back to my wallet instead they'll replace order. And when i asked to speak to their senior manager vthe girl put me hold twice but did not put me through to the senior saying that he is busy as of now, which is absolutely ridiculous. Now please help me understand why the hell would i want to repeat my order with that restaurant again. I need some strict legal action to be taken on the same asap.
