Zomato — Delivery boy giving death threats

I was waiting for my food from Zomato when I saw on the map that the delivery boy has picked up my order and is on the way. To my surprise after few minutes, I saw on the tracking map that he wasn’t moving at all and this happened for next 30 minutes. I lost my patience and called the customer care and asked them to talk to the delivery boy to know what was the matter. The customer care after few minutes called back and informed that the delivery boy is not reachable. I was famished and I didn’t want to cancel my order so I waited. After few minutes there was another customer care agent who called me and set me up in conference with the delivery boy where he said that he is just 300 metres away from me. And I kept claiming that he is 15 minutes away since an hour. The customer care was very sure that the map must be slow and the delivery boy is near. The customer care agent then asked me to contact the delivery boy to give directions till my place. I called the delivery boy and told him my address clearly to which he said that I had already informed the company when i picked the order that the location is too far and I will not be able to deliver. Well I got annoyed because he lied to me in the conference call in front of the zomato customer care agent and asked him if he can get my order or what is the option. The conversation went a way too far and he started giving me death threats saying he will come to my location and shoot me.
I immediately hung up and contacted the customer care of zomato where I showed them clearly that I was scared that he knows my address and he has threatened me. To which they replied very vaguely that he won’t get to me and we will refund.
Now my concern is how do I get the assurance that he won’t get to me when I have told him my address but the zomato agents kept saying that the location and contact number is confidential.
