Uber India — cash paid but apps considered as outstanding

Address:

Thiruvananthapuram, Kerala, 695133

Dear sir,

I have analyzed that uber dosnt have a complaint cell nor a customer based network a head to raise a complaint.in india which we are driving a service industry in our market dosnt have such kind of things is really annoying to any indian but i see they have customer cell in usa it seems.
Noting this point to the pm also to for allowing such companies in india.
My issue is related that i have been a frequent traveler and service user for uber. Recently which i have travelled in uber taxi in ernakulam city, i have paid a cash of rs 220 in which my apps is still showing that i have an outstanding of rs 218 to pay where as i have to pay via paytm or the next driver or other means it seems.
Why should i pay them if i have already paid, and couldnt find a means of demanding my views to them which was annoying. Behalf of this i was not a able to book my ride with uber because of that, which they have clearly stated me as an outstander.in this behalf i am ready to fight against their mean way defamation of stating me as an outstander.
Kindly suggest me how to go ahead on this behalf.
Thanking you
Regards
