Order never delivered and no refund made

I placed an order on the app order#86497 yet it never arrived. I have screenshots of the interaction between the driver and I in which the driver blatantly refused to de***** my order. He proceeded to mark the order as complete and took a picture, making it look like it had been delivered. I demand a refund as the order never git delivered to me. Uber and its drivers are ****** thatvare lazy to investigate into matters
