Very poor service at the time

on Monday 2nd November I had a trip to the airport scheduled for 04h25. At 04h10 the app said driver will pick up in 20min At 04h20 I received a message that the trip has been canceled. I received a second message from the driver saying he canceled cause he is too far. I then used my car to the airport and at 04h35 the driver called me and said he is at my gate. I told him he canceled and he argued with me. I have screenshots of the cancelation. Then I get billed for the cancelation and I can not find any contact method for Uber to sort this out
