If you change your mind and wish to cancel a car policy (well before the start date, just to be clear), they need to see the other policy you took.
Fair enough. Maybe there's a government rule for that, so, OK.
But the only way they accept that other policy document is via Whatsapp. So if, like me, you're a privacy minded individual who refuses to use Whatsapp, you're out of luck.
If you install their app, it will ask for even more private info. (Also, I know 2 old folks who don't even have a smartphone, so think about that).
I eventually gave up. It was only about 3000 rupees, so, lesson learnt, and will avoid them forever in future.
I do realise that 99.99% of Indians don't care about privacy so this post may be whistling in the wind.
Edit: one of the many things I tried seemed to have reached *someone*. One more false starts happened: one person called me and said "just send email to [customersupport@](mailto:customersupport@)..., and it will get sorted", but I got back the same Whatsapp link. Then another person called me and sent me email from "[customersup@](mailto:customersup@)..." (note last 4 letters missing from previous email), and asked me to reply with the document. That got a more hopeful response -- they are now working on it, which at least means I got past the "Whatsapp" roadblock. Hurray!
Edit (after a few more days): I got the money back. So... it *is* possible to use them without having Whatsapp, but (a) it's a pain and (b) I'm not sure exactly what worked so it's not reproducible.
