Dishonest Uber driver

On Friday 2nd February I took a Uber from at 10:51 am from 14 Agulhas Crescent Durbanville to the Durbanville primary school 2.1km the minute I entered the car I noticed the driver phone was off and he said it is low battery and didn't notice that it was not charging. The price of the trip was R57 when we arrived at the school I asked him now your phone is off how will you end my trip? He said " I am parking here outside the school adjust the charger, switch on the phone and end your trip. I said ok please do it. I worked at the school till 13:00. After working i wanted to order another Uber then noticed the trip was still on. I send a message on rhe app and ask the driver to please end the trip, nothing happened then I had to cancel this trip because it was going to take so mich money from my card. Now I am claiming a refund from Uber and even provided a screenshot how I asked the driver to end my trip. The response I got is " We can confirm that this trip is not eligible for price adjustment" What does this mean? If I didn't canceled the trip how much money was i going to loose? And why the driver is not explaining what happened to Uber?

Please I want my money back I was charged R179 for 6min trip which was only R57. This is daylight *******.
