I've been trying to arrange a ride with Uber and have $150 in Uber credit. Every time I request a ride I get an error message. I contacted their help desk and after 35 emails and following all of their instructions, I still can't request a ride. They still have my $150 and won't provide a refund. They keep thanking me for my patience, but after a month of trying to use their service and them still having my $150 I'm out of patience.
