No delivery ~ paid order/declined refund

Yesterday I ordered food and started messaging the driver immediately apartment number and the access code for delivery. The driver starts addressing me with the wrong name and mentions another unit number I never mentioned on the messages. The next thing I see Uber says order complete and the messages between me and the driver disappear. I demand my refund as clearly I was in communication with this driver who falsely claimed they delivered this order. Now Uber are saying they cannot refund me because I was not communicating. Utter ******* ~ your service is fast becoming *******! The proof is in the messages I was send the driver simple.
