Zomato — my money taken away by unfair means

I ordered food worth rs 156 but i was not delivered the food and the valet alleged that he called me several times and i didnot pick up but it is not true...when i talked to the delivery executive requesting for a refund since it was none of my fault, he replied in the very unprofessional manner.The screenshots of which i am attaching below. I request that some action should be taken.
