I have booked a cab from chandapura to bangalore airport. Initially the estimate was showing around rs 1500. But the driver took a different route telling that ola changed the route without my approval. The end result rs 2344 bill with rs 180+rs20 toll in stead of rs 45 electronic city flyower toll. When i reported ola had refunded rs 196. I need justice on this, where i was charged extra. Crn[protected]. The drivers name is swamy gowda. He even had mentioned that, if someone wants to go to airport, anyone can call him directly instead of booking in ola, professional rite? I had a loss of rs 800, which i need the refund.
