How to cancel the Vistara ticket booked by CV points?

[Heisenberg37]

After cancellation, how long do the points take to reflect in the account to be used again?

Ps- 24 hours DGCA rule is valid on points booking. They just deduct convenience fees.

Immediately or hardly within 30 minutes

I did cancel this morning but I have still not received any cancellation mail or points back, just received a message that my booking is cancelled.
Ill just call them again and check the status
