What's a reasonable taxi/ Uber charge for Chandigarh to Delhi?

I took an Uber from Chandigarh to Delhi- Uber app fare was about 2900 but the driver took 5570 at the end claiming tolls and state taxes.. was I scammed? It seems excessive. He dropped me in a busy road with pressing traffic saying he's very honest and can give me a detailed bill breakdown by WhatsApp message but I let it go then. Uber customer support is deflecting saying we should save the FastTag bills and only pay that total and "state tax varies place to place" blah blah so they can't take responsibility and it's on the cabbie and passenger.

What's an actual expected fare range usually? Genuine doubt.
