Bunch of *******!!!!

Placed an order in Uber Eats and CLEARY SELECTED MY DELIVERY TIME SLOT. The delivery driver arrived much earlier at my place of work knowing he is not in the time slot and im unable to collect outside the time slot. I even messaged him to tell him this. He marked my order as delivered(stole my money) left no food and drove off by the time it was 13:00 and I went outside. I tried to call him. It goes to voicemail. I reported this on the app they tell me the driver waited the stipulated time frame. When I enquired when the stipulated time frame starts from, they close my query. How did he wait when 13:00 he was not outside like he was supposed to be. Refund my money you *******!!!
