Ola Cabs / Ani Technologies — I missed my train due to the mistake from the side of ola cab driver

Address:

Anusree house, Cherapuram PO, Kakkattil via, Kozhikode, Kozhikode, Kerala, 673507

I booked a cab through ola app from mayur vihar phase 1 extension to hazrat nizamuddin railway station. The driver took a long route inspite of me asking him to take the shortest one. I was so late that there was no chance of me catching the train on time. So i asked him to drop me at nearest metro station so that i could still try catching the train he dropped me at pragati maidan metro station (From mayurvihar phase 1 extension to pragatimaidan). I lost my train which was a rajadhani express from hazrat nizamuddin to trivandrum, kerala. The ticket was of 3680.45 inr and i got no refund from indian railways. I need a compensation for my loss. I had to book another ticket of same price for two days after that in order to reach my destination. This has caused me an immense amount of difficulties and financial loss. I need compensation from ola. They're not responding to my emails regarding the issue. I deserve a response.
P. S. My ticket attached.
