Funny an Uber thread should come up. My lad and his mates ordered a cab to our house the other week, price for the journey was £17. They kept an eye on where the driver was and tracked the cab to just round the corner from our house, so they went outside to wait, the next thing the driver cancels on them. They then book again through Uber but this time the cost for the journey was £36, obviously they're not happy of the price hike but go ahead anyway, they look to see where the driver is, and the car coming to pick them up is tracked parked up round the corner, and it turns out it's only the same driver who originally cancelled on them still parked up round the corner!
When the taxi arrived my lad asked him why he had cancelled on them when he was actually only around the corner from the house in the first place, he said the driver just grumbled something and he then just drove in silence all the way ignoring their questions.
My lad was on one, so he eventually put a complaint into Uber explaining what had happened, he got the usual "We do apologise, this isn't Uber policy" etc, etc, in the end they refunded him the difference between the original fee they were charged for the cancelled taxi, and the £36 they ended up being charged.
