UberEats customer care needs a Review.

I ordered my food and upon delivery I messaged my Uber driver and asked him politely if he could come up to my apartment and deliver my food because I had sprained my ankle that day & could not walk down 3 flights of stairs. My address includes my apartment number and I also gave him the same instructions on how to get there as I have with other Uber drivers which they have all followed perfectly fine. My delivery man messaged me saying “please come” after I asked him, he then proceeded to cancel my order and drive away with my food because I explained again that I could not walk down & collect it. What I’m most concerned about it why Uber Eats does not have anything in place for this? Why do you lose all of your previous deliverer orders once cancelled? Why does this happened so often? And why can you not suspend the driver from using the app if they do something like this unreasonably? When going through the help, there was no way for me to make it known what happened and who the driver was/what their details were.
