Ola Cabs — Ola cab drivers denying service

On 09 Jun 16, i have booked Ola Cab Service five times starting from 2240hrs to 2257hrs. The reason behind booking for the cab service five times is the repeated denial of service by the Ola Cab Drivers. Following is the List of Ola Cab Drivers who denied services requested for:-
Driver Rakesh Vehicle No. HR55X2227
Driver Gaurav Vehicle No. UP16DT5771
Driver Aftab Vehicle No. HR55X6723
Driver Satish Vehicle No. HR55X4970
Driver Rohtash Vehicle No. UP16 CT7980
These drivers not only denied for the service but they did not bother to call up the person who booked their cab. Every time i had to call up using my personal phone on their numbers to find out their location and requesting for the service.
This seems to be a very sorry state of affairs for a Cab Company who is projecting itself to be a prime service provider in the recent times.
It is requested that strictest of the action may be taken against the above mentioned drivers which should become an example/deterrence for the others.
I hope the action taken by your company will result in not letting another individual go through the same suffering which i had undergone on the night of 09 Jun 16.
Awaiting your response.
