I gave a passenger a five star ratings (I could tell he's a jerk in real life but he was pleasant enough on the drive) He ended up leaving his phone in my car. I went out of my way to bring it back to him and he gave me a one star. I just started driving and had a 5 before I picked him up so I figured the math and know he gave me a one. Is there a way to change my rating or at least make a complaint. Uber should be able to track people by complaints instead of just ratings. I have a feeling this guy could be a real jerk to other drivers.
