Unfair Overcharging of Trips

It's great until it isn't. I don't understand why my trip fees is changed from R90 to R170 and I don't get reimbursed for it. Accidents on the road, road work etc. should not be held accountable for on the part of the passenger. Sometimes even the drivers themselves fiend the route then the trip ends up being more. This is total ******* #BlackFriday
