UberEats incapable/unwilling to resolve serious saftey concern

I have raised a serious safety concern with UberEats and they are not taking it seriously. I have been previously assaulted in my home by a ********, and as such I am very nervous to open my door to strangers like UberEats drivers. I use the Leave at Door option when ordering from UberEats - easy enough, right? Lately the drivers ignore the instructions, insist on knocking and demanding I open the door (which I refuse to do due to the previous trauma) and I end up having a shouting match through my door with the drivers, loading a panic attack on my side and disturbing my neighbours in the process. It's such a horrible experience and one that keeps happening. I asked UberEats if they train their drivers to do delivers as per instruction to ensure their customer's safety, and UberEats REFUSES to answer what is actually a very simple question. I have sent MULTIPLE messages and emails to every available communication channel - and nothing. I have gone to the ends of the earth trying to find a resolution, it's been several weeks and way too much effort on my end. It's clear - Uber Eats does not care about this security concern and are happy to copy and paste generic responses without taking any tangible action. While I used to order Uber Eats multiple times a week, that will no longer be happening. Deeply disappointed that a brand of such global stature can act with such indifference.
