[2020] i didnt get my 1,000 vbucks from fortnite crew

You can check the Fortnite Crew screen in-game (go to the Battle Pass Tab and select 'Fortnite Crew') to see when your V-Bucks are expected.

1,000 V-Bucks grants are delivered monthly from the day you first subscribed. For example: Signed up on December 5th, 2020? Your second V-Bucks drop will be granted January 5th, 2021, your third February 5th, 2021, and so on.
