Zomato — order not delivered... money not refunded

Address:

Nellore, Nellore, Andhra Pradesh

I have order one item through zomato with order id [protected] on 15.01.2020. The zomato delivery person came and was there in front of room. At that time beacause of some issues... My no was not reachable as they r saying... Then after being late i checked online to see the status.. I saw it was in my location.. So i went out... At the same these zomato people they themselves cancelled the order and that fellow went without hearing my voice...
In my order address.. The door no was clearly mentioned... He must have seen the door no also.. But he didnr knock the door and he didnt even get down from the bike i think
With in some moments.. They cancelled my order and that fellow went with my food.. And now they r telling they cant refund the money as it is already prepared.. Such nonsense the service is from this company
