Ola Cabs / Ani Technologies — over charged and accounted debited

I booked a ride from chennai airport to ramanujam it city which is around 14-15kms. When i booked the ride the peek price shown was 450 but i was charged 1000 from my ola money account. Usually the ride costs 300-400; i am not sure how can a company charge 3-4 times; was the charge based on my ola money balance? What if the balance was 5000? I am being by customer service when i log the complaint that the peek price was 1000; i am confident that i saw 450..
