Ola Cabs — False commitment and Lacking trust

I booked Ola taxi on 3rd April for a ride on 4th April Morning 5.20 for travelling between L B Shastry Nagar to Cantonment railway station. I got confirmation message that cabs are available. CRN72487026. Even I got driver and cab details in morning 5 AM. Driver called up and asked about pick up point. I said L B Shastry nagar near HAL. Driver denied that he is at Richmond road and too far to come and pick up. So, he can not come and asked me to look for some other cab. I said should I call call centre to find another cab. He said he will try to come, which was false promise. He never turned up. I got cancellation message soon after that. Problem does not end here. there were two numbers to reach the driver. On one number he did not pick up further. And another number, I was not able to reach at all. Even he has did some thing, I could not call the call centre number also. Till now, I am not able to call call centre to book any further cab also.
