Uber India — toll amount overcharged in invoice

I took a ride in uber on wednesday 5th september from electronic city to yeshwantpur. Driver took nice road and asked me to pay all tolls. Later when i checked invoice i understood that uber had charged me rs204 extra in invoice as toll charge, luckily i had all toll bills. I immediatly raised issue with uber help team but they are ready to refund only rs 150, despite submitting all neseccary documents. Very unpleasant experience and loss.
