Hi,

I book an Uber cab on 05/05/2018 from Kukatpally to Rajivgandhi International Airport . That cost me 1116:63 and driver asked me pay through the cash. I said it showing paytm. Driver said there is technical issue in paytm payment so it won’t charge from Paytm. I paid through cash . After 8 days ( 12/05/18 ) they charge me again from paytm. I try to contact them from Uber app. But they r not responding. How come they r charging twice . No contact number for Uber customer service.
They r violating all the rules.
