Uber India — uber travel charged without travel

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I booked a ride on uber and i got confirmation that my ride is booked. I called the driver and he told that he is coming. I wait there and he was raming some around. Suddenly i got mail and of receipt o[censored]ber drive and notification that my trip is completed and have been charged by 28 rs. Although it's a small amount but i didn't take ride and he completed the trips.. It was an online payment. So where is security of payment..
