Uber India — wrongly charged interest on fee already paid

Facts-
I took a trip on 24th Jan, 2019, the total distance was 2.1 kms, ride time was 5 minutes. I have paid 69 rupees in cash (screenshot attached)
Problem -
Now uber kept showing me a fare of rs. 680 everytime i tried booking another ride subsequently saying its outstanding.

I checked all my past trips, found no trip of the said amount, wrote to Uber. Now I have learnt through my own investigation that i am being made to pay interest on a fare i have already paid, this 69 rupees has now become 750! If i have already paid this in cash, why is uber charging me interest for the same?
