Bad attitude

I contacted Uber to collect my wife from Groote Schuur hospital. They did respond quickly and advised a driver was on his way. I amended the collection site to the correct place on the internet and tried calling the driver on three occasions to confirm the pickup point. I tracked the driver going down the incorrect road and tried again to contact him via sms and via his cellphone. On all occasions, it went to voicemail. He made no attempt at telephonic contact and then just cancelled the trip. Very poor service from Uber and their driver. What is the point of having a cellphone and sms contact when neither is functional. The driver must have had his cellphone on to receive the notification of the trip.
