Swiggy — items missing on the order

Address:	Swiggy, 560008
Website:	www.swiggy.com/support

I placed an order today 22/11/2019 for burger from burger king through swiggy.
I placed order for 2 burgers and 1 combo pack.

I did not receive the items that included in combo
I raised a complaint for swiggy and the response i got is that i will be getting rs 30 as an apology...

I paid 154rs for the combo and for 2 items (Fries & large pepsi) they are saying that they will provide 30rs coupon... So they are expecting me to pay rs 120 for 1 burger. Which is not acceptable.
