My children left stranded.

I have been using Uber for a while now.... mostly because I feel safe and had 100% trust in them. To get me, or my kids home safely. But last night was absolutely shocking. My son and 3 friends went to Ultra, I dropped them all off because it was still light and safe for me to do so. With the comfort of knowing I could app uber to bring them home. The first driver cancelled on the app 2 minutes after dispatching. The second one spoke to me on the phone, got his number and got my son to call him. when he called, the driver told him that he cancelled as he couldn't get hold of me. This left 2 young men, and 3 young ladies stranded on the N7 In the middle of nowhere and I was too scared to drive there on my own to get them. I am so disgusted. Especially that Uber was supposed to have Partnered up with Ultra for this event and that this driver was 4 minutes away. If I wanted an unsafe, unreliable experience I would have called them a normal taxi service.
