Very disappointed with Uber Eats support after a recent order from KFC Three Rivers

Very disappointed with Uber Eats support after a recent order from KFC Three Rivers. The driver contacted me when nobody was home yet. I responded immediately and asked him either to place the food safely over the wall or leave it with neighbours. He refused both options and instead left the order unattended on a public sidewalk. He indicated that someone would likely take it. I immediately tried calling him back, but he ignored my calls. When the recipient arrived about 2 minutes later, the food was already gone. Uber Eats support keeps responding with generic copy-paste replies claiming the food was left in a “secure location,” but they refuse to explain how a public sidewalk qualifies as secure. This was not an address or communication issue. I was actively communicating with the driver and provided reasonable alternatives which were ignored.
