Ola Cabs / Ani Technologies — charge much higher than estimated fare

Address:

Bangalore, Karnataka

I booked a cab on 10th nov, 2018 and the estimated fare was rs. 273. But i was charged rs. 702 which was more than 50% of the estimated fare. I conveyed the same through their support mechanism
But there was no resolution. I also tried to call ola support but couldn't get in touch, the call gets disconnected every time. Their support mechanism is very bad and it's very difficult to get in touch with them
