Uber Eats complaint: Delivery driver left food on random pavement

On March 10, I ordered a pizza and drink through Uber Eats and the driver called and said he couldn’t find me. I am currently undergoing chemotherapy so shielding but he was very close so I gave him clear directions. He called back a few minutes later saying he still couldn’t find me and was outside a pub. He had gone further away but I gave him very clear directions again and he said he knew where I was, next to the back of the police station. A few minutes later I received a photograph of my pizza lying on a pavement and a message that he had delivered to exactly where the food was ordered to. I tried many times to call him back but he refused to answer and then blocked my number. I complained to Uber Eats who agreed that they could see we had been speaking and then later said that he had tried for too long to find me and they didn’t seem to care that my order had been left on a pavement. They refused to refund my money including the generous tip I had included for the delivery guy
