Ola Cabs / Ani Technologies — cancellation charges of booking cab

Yesterday i, booked a cab. On contacting to the driver of my booked cab after 3-4 min. He told, he has no info regarding booking, pls wait when i will get info will reach to your venue. But after 4-5 min. I contacted him again. He said i still not have booking may be because of some technical issue. You just cancel the ride and make fresh booking. On doing so i got message regarding cancellation charges of 50 rs. Which i have to pay on my next fresh booking.
Now my concern is if driver is not willing or not getting details then it is not my fault. Why i should pay cancellation charge.
