Incorrect pricing

Completley ****ed.... bolt showed me R61 for my trip there after i ended the trip amd it was R81 bare in mind i didn't add any other additional stop nor did the driver wait lomger than 5 minz how did the amount end up R20 extra i don't know check if urls drivers aren't rigging the apps this is unacceptable not that R20 makes a big difference but y have 1 amount n change to another when there was no addition routes or time standing prior to the destinations!!!!! Apsoloutley ****ed at how bolt is turning out !!!!!!!!
