Ola — paid ride amount but claiming I haven't paid

Address:

Mumbai City, Maharashtra

I had booked ola from mumbai airport to lodha palava, dombivalli (Early in the morning). Completed the ride (Through longest route, driver claimed that other routes are with traffic jam) paid him what he claimed (My mistake was i did not received any message but paid him). Later after 10days or so, i was trying to get bill, to my surprise it shows "ongoing". When complained, ola team said i didn't pay my charges which is out right lie.
No one has contacted me and checked but declared that i have to pay, though i had paid already.
