1st for me.. What do you do?

I had a pax cancel a ride on me while in route to the airport about 1/2 way there. The fare was supposed to be $48 and uber credited me $7.. I asked for a fare review but got 0 response from uber. I am not going to put the pax out in the interstate but needless to say I was not happy. I bit my lip till it bled only to keep my 5 star review. Just curious as to how other drivers are handling that kinda stuff?
