I straightaway lodge complain to Uber. But I wasn't charged la, just wanted Uber to know about him and save other riders the hassle

As to other drivers here, mind explaining why accept request and then don't pickup?

I once had a uber driver that circled the area a few times and he couldn't find the location although the specified pick up point was accurate. He just couldn't understand my directions when I asked him to stop the car and wait, I will walk to him. I ended up cancelling because there was a grab driver in the area and he called and yelled at me. I was really rushing and didn't need to be driven by an idiot.

Another incident involved a grab driver. He arrived and went straight into the condominium when I specifically told him that I am already waiting at the main road. He then called and rudely yelled 'SUDAH SAMPAI LAH, LU MANA AH?' When I entered his car he continued his tirade telling me that I should have been at the location before bidding for a ride. I told him to stop the car, I got off and told him to 'F off'.

One of my students, a Bangladeshi guy was racially abused by a driver who asked him to get out of the country.

I think that while the majority of drivers are nice and decent people the number of assholes are on the rise lately.
