Swiggy — Order No #[protected] not delivered

I had order food today at approx 9pm from swiggy chaska restuarant which is nearly 5-6 kms from my location. I received a message from swiggy at 9:56 pm the food has been delivered but actually it was not. I called the delivery executive many times he was just giving me excuses like i forget the route, i came to some other place by mistake.
When i asked why have you pressed delivered food option from app when it’s not been delivered yet he told me that it was done by mistake !! Okay I accepted it and i started telling him my location verbally through call . Then after 15 mins, from his location delivery address is near around 2kms i.e., hardly 10 mins from 2 wheeler. I called him again to know where he is. He gave me another reason that his bike stopped due to low fuel and previously 10-15 mins back i called him he told me he was at gas station & now he’s telling me that he is having low gas in his bike. I myself drove my car to his place and asked him for my order by showing my order id. Then he said he does not have my food with him & he’s not carrying my food. Also he has consumed alcohol and smoking weed in front of me that delivery guy was unable to stand straight and was unable to drive his bike carefully while he was leaving from there we noticed.
And one more thing, he said his bike has no fuel but he started his bike in front o[censored]s and left !! If his bike has not fuel how did his bike started ? I’m really pissed of with the behaviour of delivery executive as he was drunked smoking weed in front of me and has not delivered my order I’m still sleeping empty stomach.
