Domino's Pizza — Refund issue and threat calls from staff

I Ordered From Dominos Yesterday As The Order Was Showing Guaranteed Delivery In 20 Mins So I Asked Them For A Refund On Receiving The Order Late First The Outlet Representative Tried To Manipulate Me With The Wrong Terms And Conditions And When I Read Them From The App Properly He Agreed To Give 200 Coins As Per Rules.
When I Didn't Receive Anything Till Now So I Wrote A Mail To Dominos To Officially Handle The Case.
After That The Same Staff Started Calling Me And Again Manipulating The Rules When He Couldn't Win The Argument With Fake Points He Started Using Bad Language And Also Threatened Me For Not Being Locally From This City (Bangalore).
