I had a different issue with my charge
When ordering a trip, you can see its upfront fare that includes a number of predictable factors. The calculation of the fare is done dynamically, therefore it may vary for the trips with same addresses, but requested at different times.
If addresses of pickup location or destination were changed and there were additional stops, the fallback of the upfront fare may take place. In this case calculation of the fare is made taking into account the base plus rates for time and distance. If you make a request for the ride during times of high demand, the fare already include surge which will remain unchanged if there will be the fallback of the upfront fare.
Please note that we do not recalculate fares of the trips in which fallback of the upfront fare was caused by described factors.
If you are sure that the fallback took place incorrectly, report this and describe the details of the situation.
