Very disappointing

I am very disappointed in Uber. My Scheduled ride confirmation email arrived but not my driver, nor the subsequent drivers that left me stranded at Sunday, May 9, 03:20 AM on the side of the road. How does a email confirmed scheduled booking not turn up? Your help desk phone lines were too full to take calls. I booked again and subsequent 2 drives cancelled even though the app confirmed the ride.. Do not use nor support Uber. When it goes wrong there is no support and no-reply email addresses. Uber has become another faceless soulless corporation.
