Swiggy — issue with the order

Address:	Hyderabad, Andhra Pradesh, 500033
Website:	www.swiggy.com

I have placed an order from mcdonald r. K. Cineplex hyderabad at 12:07 pm on 21st feb 2018. After around 30 minutes, i got a call from swiggy and asked me to cancel the order, before i finished my queries, he hung up the call on my face, and cancelled my order.

How the hell can he cancel my order before getting a confirmation from my side? How can he hung up the call when i am not done yet? Is this the service you provide to your regular customers? We order in bulk quantities twice in every week and this is the way you handle your customers?

I want an action on it as soon as possible or i'll raise another complaint to higher level.
