Ola overcharging through malpractice & bad policies

This is regarding Ola Cab services (ANI Technologies Private Limited), the app based cab provider company in Delhi-NCR. I used to travel from Delhi to gurgaon (NCR) & vice-versa and also Delhi to Noida (NCR) & vice-versa.

I booked cab on 25 Apr, 2016 at 08:39 PM from Gurgaon to Dwarka, Delhi and was charged Rs 319. The booking id is CRN227644706. The bill breakup showed State Tax/MCD charges at ₹100. I raised complaint that since the MCD charges should not be borne by the customer, the Rs 100 amount should be refunded. I got a refund of rs. 100 after reaching to them through social media (twitter). The complaint ticket is #4468627.

On 30 Apr, 2016 at 09:55 AM, I booked cab through ola cab again from Dwarka, Delhi to Sec-126, Noida. The booking id is CRN231576316. The bill breakup again showed State Tax/MCD charges at ₹100 and Toll/Parking Fee at ₹28. I again raised complaint that since the MCD charges should not be borne by the customer, the Rs 100 amount should be refunded. But this time they were not ready to refund citing that the customer has to pay State tax as per their policy. I kept saying them that I am ready to pay toll amount of ₹28 but why should I pay MCD charges which is charged to commercial vehicles and since you are running a business of point to point drop, these should be borne by the Cab owner or the service provider (OLA). I had discussion of over 15 minutes at least two times and wrote them on social media (twitter) as well and the email exchange is still in progress on complaint id- #4831409. I even emphasized on the fact that its not about refund of Rs. 100 but about wrong practices of looting customers, the grahak.

I asked them couple of questions as mentioned below, but never got reply:

1. If the cab make 6 trips from delhi to ncr, would you charge 100 bucks to each customer as state/mcd tax? Please clarify.
2. You accepted the mistake and sent the revised bill after refunding 100 bucks. Check #4468627. Why so?
3. I only travel from delhi to ncr and vie-versa, how come I was never charged this state/mcd tax before and only since my last 2 bills? My last bill was also rectified (CRN227644706).

Till date, I have not got any reply to these logical questions from them. Since they do not have any escalation matrix or Grievance redressal mechanism in place, its tough to reach the senior management and explain them their unethical malpractice of overcharging on the name of company policies.

I have 2 requests:
a) This policy of charging MCD tax from the customer should be abolished right away since OLA is running a point to point drop business and not a charity and it has to be borne either by them or the cab owner.
b) I should get refund of Rs 100 immediately.

I have all the evidences in support of the above mentioned facts. Kindly help.
