Swiggy - Order cancelled without information

I have ordered on **th April and these people have cancelled my order after * hour without informing me. They actually have wasted my time in between an hour. Today I have spoken with them. They easily said that refund has been cancelled due to address the issue. It's really the worst experience with Swiggy.
I would recommend uninstalling this app as soon as possible. Such a worst app with cheap delivery executive and customer care people. Such a bad user experience. Swiggy should terminate such type of people. I have two complaints about their delivery executive and Customer care team.

*. Their delivery executive does not have any idea about the nearby location. When he was near to the restaurant. I called him to reconfirm the address as my profile address was correct and Swiggy map was with the incorrect location. Delivery guy is saying, I have no idea about where I need to deliver the food what to deliver. I am not sure why Swiggy team hired such type of people as their delivery guy do not know where to deliver what to deliver and when to deliver. Looks like even they do not know what they are doing after joining swiggy. Also, I requested that guy to come down to nearby landmark so that we can pick the order. But without listening to my words they are just disconnecting call using rude statements. Even they are not picking up the call multiple time.
Swiggy Delivery Guy No: **********
*. When I was chatting with customer care for this issue, they simply ended up my chat without reading my response. Such a worst experience so far with swiggy.
They are just ignoring the customer's request.
Customer care people: KT_Anirban Paik and Sanjoy.
