Ola Cabs — Did not receive invoice & misbehave of CCE

I had opted your service on 1st June 5, 2015 from hotel Formula 1 to Pune airport. But till now I did not receive the invoice. Two times I called to your call center & was told that the email Id is rectified and invoice is send. But I am dishearten by your call center unprofessional service, the CCE & his team Leader who received my call at 12.59 released my call instead of giving proper service. I have make the mistake by taking your service. I will definitely inform all my known person to hire Meru cab instead of OLA. My email id is [protected]@hotmail.com or avirjyoti.[protected]@wipro.com
