Uber - CANCELLED TRIP BUT STILL YOU GET CHARGED

Extremely livid at the lack of contactability and response from Uber SA. My daughter booked a two stop trip last month and the driver simply refused to do the second stop. She was however charged for the full trip. The driver informed her that she can log a call with Uber for a refund. There is no contact number and the Help option on the App is useless - they send a one liner response and then nothing. Totally disgusted and disappointed!!
