Uber India — billing for a trip where I did not travel

Address:

Mumbai City, Maharashtra

Had booked a cab at mumbai airport international terminal t2 on 21st may 2018 at 9:06 am. The cab never turned up. I went to the uber counter at the terminal who advised me to cancel the booking and make a fresh one. To my shock, uber has billed me rs 248.69 for a trip which i never made. The counter person advised me to submit a refund request from the mobile app but have not received any revert from them. I booked another 9:28 am and it was a repeat of the same story. I was billed rs 123.66. On both occasions cab never arrived. Yet my paytm account was debitted for the same. I am planning to file a section 420 case of cheating and fraud against uber.
