Swiggy — Swiggy cancellation policy

Address: Gurgaon

I have ordered something from swiggy and selected wrong address. They have no option to update the address, and these guys took whole amount as cancellation fee. I really don't understand what this policy is., atleast they should have another option, can charge half amount as cancellation fee.

I am fed up with their services and have uninstall swiggy.
Amount charge 284 as cancellation fee.
