Swiggy — swiggy cancelled my order without my intimation

Address:

Chandigarh, Chandigarh

I ordered food from swiggy and executive reached the location and refused to come upstairs to deliver my order and when i went downstairs he went and said do whatever you wanna do and abused, guess he was drunk. His name was ravish kumar. When i contacted customer care, they said delivery executive said location not found though swiggy has already delivered me n number of orders there.
This is not first time this is happening, this happened twice earlier where they were unable to deliver the order and gave me a coupon of 100 rs.
But this is limit now
