Description: i had taken a ride at above date and the total fare was rs.221. at the end of ride, i had asked the driver to take the money from olamoney. however, as the olamoney balance was low, the fare was deducted as rs.162 - olamoney and rs.59 - cash. but the driver asked me to pay 162 by cash and as i was in a hurry i paid rs.162 and gave a rating of 5 stars to the driver. however, i later on checked and found out that i was supposed to give only rs.59.
When i called on the mobile number provided by ola, some other family member received the phone and told that they would handover the phone to that driver but the phone got disconnected. now, the driver is not receiving my phone and purposefully disconnecting the phone. i tried to connect many times.
