Whats happened to uber??

Ive been using uber for ages, but last 2days ruined my impression completely. Yesterday I ordered uber to go to work and when the car was 2 mins away, for some reason the app cancels the trip and orders a new car. The driver still arrived, so I explained the situation. In my history I dont even see this trip (cancelled or not)
Today I ordered uber again and when the driver was 2 mins away and quite close on the map, the app starts showing 1 min left but the drivers car is when he was when I ordered him - 13/14 mins away and doesnt move , even after I close and open the app again. I waited for few mins and no one came so I had to order a local taxi
