Swiggy — coupon code description/bad customer support

I placed an order today, order #[protected] on 14th may 6:55 pm.

The restaurant page showed 35% discount with "swiggyit" and 5% for super members. However, since i did not understand how the discount was calculated, i contacted swiggy chat.
I chatted with 3 executives but none of them was able to provide the breakdown of the fees. They kept saying that even they dont know the exact breakdown. The second executive that i chatted was more rude as he closed the chat while i was still asking question (Attached photo).
Also, when i asked where is the terms and conditions for "swiggyit" on the app itself, no one could provide.
I had an extremely bad experience and felt that i was being lied to.

Request:

1. Share the exact breakdown of all the fees for order #[protected]

2. Share where the terms and conditions of "swiggyit" is shown on the app.
