Ola — Ride cancelled by driver/ driver not picked up call

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

Hi,
I booked a sharing cab yesterday morning. I got a msg after booking confirmation.
I called up driver & asked where he is? Driver said he is near to my place and reaching soon. I called up after 15 min he said i am not able to identify the root.. I explained the root to him (He was behind my colony). And after 2 min he cancelled the ride by stating that he is not able to find out the root.
I again booked 2nd cab & 2nd driver also cancelled the ride with the same reason.
It has wasted my 1 hour & i got late in reaching office which resulted a cancellation of my important meeting.

This is not happening for the first time, few days ago i booked a cab & driver did not picked up my call (Called up 10 times). & the i got a msg from ola that driver is waiting outside.. But there was no one waiting outside.

Whats the point of providing the facility if your driver/ ola can not provide the service?

This is really really disappointing!!
I would

I would not prefer/ recommend to use ola cab anymore.
