Why have I received the Fortnite Crew Pack items and not the 1,000 V-Bucks?

As a member of the Fortnite Crew, you will receive the Fortnite Crew Pack on or around the beginning of every month. For most players, the 1,000 monthly V-Bucks will be received at a different time as the Crew Pack. This is because the V-Bucks are added to your account on the day of your billing, which can be any time of month depending on when you signed up.

For example, if you signed up to join Fortnite Crew on the 5th of the month, you will receive the next grant of  1,000 V-Bucks on the 5th of the following month, upon successful payment, and so on.
