Uber eats is scaly

I am so shocked at the dishonesty and audacity of the uber eats delivery boy. I'm in a wheelchair and receiving treatment for cancer in hospital in cape Town and all I wanted and was craving today was a pizza. I ordered a pizza, payment went through. I stipulated in detail where in the hospital I am. 20 minutes later the delivery guy called saying he was outside the building. One of the nurses here went outside to find him.he called several times again saying he's lost. I told him to please wait, a nurse will pick up the order. He put the phone down.the nurse came back and said there was no sign of any delivery man. When I tried to call him, the call switched to a voice mail saying the number doesn't exist. Immediately hereafter, I received a notification that the order was canceled! I paid a hefty amount R155- for a small pizza I never received and wasn't refunded for in my bank account! I want answers and my money back. I'm deleting the Uber eats app and only using mr delivery now.
