Ola Cabs / Ani Technologies — ola driver used bad languages

I booked a ola in siliguri on 13th may 2019 from rashbehari sarani hakimpara siliguri to neotia het well healthcare matigara with crn [protected], drivers name was dipon biswas. My wife was suffering from drug allergy and needed immediate doctor attention. But he simply refused to pick up due to unknown reason. His tone of talking to my wife was very rude when contacted over the phone. If he was unable to pickup he should have said the same politely. But instead he abused my wife.
It's my earnest request to you to kindly take some steps against such drivers or else your company's reputation is at danger due to such drivers.
