Cancel Trip

Yesterday I took Bolt when I was going home, I booked it start by droping me off and take my friend home, unfortunately while we were on the way to drop me off my friend had to go back to where we were so we dropped him off on the way and we contiued with our trip, I asked the driver to cancell my friends trip, when I check on the app this morning they still charge me for that trip and the pick up point and drop off point are totally wrong.
