OLA - Ola not refunding my money instead to raising multiple complaints

Let me explain you the complete scenario. I took a ride of Ola outstation on **th May early morning * am. The total distance was *** km but Ola Driver entered *** km. So, the total fare should be **** Rs but ola app calculated it as **** as the km entered by driver was much higher than actual. So, **** Rs is paid through Ola money and *** I paid through Google Pay and I also paid *** Rs toll tax to him which is way higher than the actual. so, in total I paid **** Rs to Driver through Gpay and **** Rs to Ola money. Now when I raised a complaint to Ola cab they should have refunded (**** – **** = ****). but they refunded only **** Rs. So, remaining *** Rs still needs to be refunded. And Also here I have let go the *** Rs which Driver took from me for toll which is not at all correct.
