Appalling customer service

Placed an order for some groceries from Ubereats and I scheduled it between 2 and 3pm. The driver arrived and he tried calling me but I was in a meeting. He only called me once and I missed the call as he got here at 2:03 which I did not expect. I got a message saying be dropped my food on the road, I ran outside to check and nothing was there. I then complained to Ubereats because how is it allowed that the drivers can leave your food on the road, I do not even live in a gated community, I live in the suburbs so any vagrant would pick my things up and leave with it. I then checked my cameras to see if perhaps someone had taken it in the few seconds it took for me to run outside and then discovered the driver took a picture of my parcel in his scooter and actually just left with it and essentially stole my things. I contacted Ubereats and they told me he followed protocol and waited 9 mins before leaving the food at "my gate" on the road and I told them I saw him leaving with it on my cameras and the response remains the same. On another note, 3 of the items I ordered were out of stock and they haven't even refunded me for those items. I'm done with Ubereats and would advise people to stay away as they clearly condone theft and refuse to take responsibility
