POOR APP SERVICE FROM THE UBER APP

My partner and I requested a ride on the 10th of April. The request was from Orlando to Vosloorus. We used my partner's phone as she had discounts. The fare was R256. The driver was all good and the ride was perfect until we've reached the N3 route to Vosloorus. the Freeway was blocked due to a strike. So the driver suggested we use an alternative route and he knows he's way around the place. so we went all the way around through Alberton and it took even longer. when we Arrived the trip fare rose to R385.00. we told the driver its both not our fault but our budget was R256.00. we both settled at an amount of R300.00 instead of R385.00. the driver understood and said he will report the matter and it wont be a problem. 2 days ago my partner and I try to request and the app said we are still owing R85.00. The strike wasn't anyone's fault. but why are we being punished??? i mean if the app prices can Go sky high when it's a rainy weather... you mean the app cant provide alternative routes when we encounter such problems. cause all the routes we tried kept sending us BACK to the N3. AND IT WAS CLOSED. so today we are being punished. That service was unacceptable.
