Uber India — charged twice for same trip and not giving refund

Address:	Ernakulam, Kerala, 682012
Website:	Uber

I had taken a trip on 21st may 2018 at 3:58 pm from pottakuzhy road to cochin international airport. I was charged rs.445.52 for tge trip which i paid using tez app (Upi).
When i tried to book a cab the next day, i was asked to pay again. I had to pay it again as i wanted a cab for commuting urgently. This time i had paid using paytm. I raised a complaint in the uber app. The customer service agent replied asking me to attach the screenshots of the bank statement and the paytm app. Inspite of trying many times, the uber app wasn't attaching the screenshots. I requested the agent send me uber's email address to which i could attach the screenshots as the app wasn't uploading any pictures inspite o[censored]pdating it as well. She just assumed i am unaware of how to take screenshots or attach pictures and just sent me some guidelines on that. I informed her again that it wasn't my mistake that uber app isn't attaching any picture that i tried attaching. There hasn't been any response from her or uber since.
I need my money back at the earliest. I am attaching the screenshot of the trip details,, myank statement of 21st may and the paytm app statement of 22nd may for your perusal.
