I don’t know how Amazon works but I imagine it’s some sort of form submission and she chose the wrong option.
Don’t think that makes it okay, time off requests should be considered by a human who actually interacts with the employee, in my opinion, but I can see it happening. Dealt with that when I worked for Walmart. I definitely got a few days off that I submitted through the automated system online and have no idea if anyone ever approved.
Holy shit your horse is tall
