Ola Cabs / Ani Technologies — overcharging due to deficiency in services

I am writing below an incident of ola cabs which is an act of deficiency in customer service, overcharging fare and rude driver. The case was informed to ola help desk whose reply was grossly insufficient and customer service executive mr. Dexter cited his helplessness due to company policies. Subsequently i told him to respond in writing and escalate the case to his manager for further discussion he replied that he cannot do that and he is the last level of escalation. I was asking him to make partial refund of fare charged to me for deficiency in service which was straightaway rejected. These kind of response by such large e commerce based companies actually results in more arrogant partners, profiteering by company and suffering customers. Infact at the end i was feeling cheated by the company. It looks like that these kind of acts are frequently followed by company where there is no customer care to connect at the will of customer and ultimately he had to suffer.
The whole incident is narrated below:
I booked ola rental can on 5th march 2019 which implies ac cab was ordered. I was allotted cab with following details:

Car: white swift dzire
Driver name: radhe shyam yadav
Car no: rj 14 td 4347
Crn no. [protected]

I started with the trip and told driver to start ac since co-passenger was having allergy to dust. The driver informed me that vehicle ac was not working. We insisted the driver to switch on the ac and noted the same. When someone books ola cab it's implied that customer booked ac cab, ola charged me for ac cab as hire charges which is incorporated in fare by default.in my case when i told this to driver, he behaved very rudely, infact, asked us to leave the cab on the way.
I could not connect to ola customer care due to their business model where customer can't connect at his will. Driver was too rude to speak and he threatened me to stop the trip in between. Its an unacceptable standards of service by ola as well as driver. On raising complaint i got call from customer care and they simply resolved the case by telling me that they have warned the driver. Here i paid full amount to ola for deficient services. On asking the customer care to repay suitable partial amount, it was refused by stating company polices. This simply gives the sense that company promotes its partners to do this frequently to reduce its cab service cost. But ultimately customer feels cheated. I need suitable tangible action from ola in form of refund of suitable amount for deficiency in services.
