Uber India — though the trip amount was paid in cash, uber deducted additional 700 from paytm.

I have travelled in uber taxi in bangalore on 10-may-2018 to airport. Due to problem in the driver mobile the amount was shown as 23/-. Where as in my mobile it was shown as 874.20/- i paid the same 874.20/- by cash. Whereas the receipt i received was for inr 23/- then i approached the uber help to review the fare and issue me the update receipt. After few conversations, the same was agreed by helpdesk, that it was due to technical glitch. However later one fine day in my uber app it started showing as inr 700/- as outstanding for that trip. I again raised a concern stating that this is not correct and i had paid the total bill amount in cash. They responded as they will look into the matter. But on 9th june 02:00 am they have deducted inr 700/- from my paytm, which was also another mode of payment in my profile.
When i approached them they reply saying that the trip payment mode was in paytm, hence deducted, and as it was done out o[censored]ber system, they cant reverse it.

Please review and help me in this regard by either uber to reversal of amount or uber to have inr 700/- as balance in my account so that i can use them for later trips.
