Mutual fund NAV date clarification

I want clarification on applicable NAV date for investment made in mutual fund. I invested some amount in particular mutual fund through online brokerage app. But I got the NAV of next date even though I invested as per cut of timings for that app. I think that online brokerage app don’t sent the money same day to AMC. I want to know where I should make a complaint regarding this.

you will have to get in touch your broker to know more about this in detail. you will be able to find some option to raise an issue on their portal.
