Requested a trip yesterday and my payment option was card, seems the service was offline at that time,however money was debited off my account but wasn't located to a driver to come pick me up. Requested for the 2nd time and still the same amount of R113,00 got debited and a message popped "your payment option is currently un available " I then decided to change payment option to cash,that's when a driver was located by the app to come pick me up.l paid cash for this trip however a total amount of R226,00 was debited from my account already. I haven't received my refund yet and have logged in 2 complaints already on support with no responce..
