Swiggy — Wrong order delivered twice and no resolution.

First I ordered crispy chicken momos and mutton club sandwitch, but I received Veg crispy momos and chicken soup which was a waste for me. Then they replaced only Sandwich with soup, and again I got another order. I contacted customer support and the agent asked me to wait and she'll be transferring the call to her supervisor and disconnected it, then other agent came and did the same, tried further contact but unable to get anyone.
