Ola Cabs — Upgraded without my consent

Address:

Mumbai City, Maharashtra, 400097

I have been using an ola cab (micro) since 8/9 days for the same route, ie between goregaon east and juhu. my tariff approximately is around rs 140 -145. however, the days they announce a free upgrade i am charged 10 to 15 rs extra. please explain why so. however, today i was again given an upgrade and charged rs. 226. i later got an sms saying that i will be charged peak hour rates (4*1). can you please explain this?

I did not ask for an upgrade, so how have you decided on my behalf and why should i pay extra. if i am opting for a certain option, then obviously it is due to a certain budget in mind. how can ola upgrade without my consent and then charge me extra.

I need a refund for the amount charged extra and an undertaking that it will not happen henceforth.
