How to get Vbucks in fortnite save the world

I bought save the world because I wanted to earn Vbucks. Then I saw that I somehow can't earn any Vbucks on daily jobs, and I also didn't get any Vbucks when I made collection on level six. Why is that with me?

So i think after 28 days you get 300 vbucks i just go in once a day and get the rewards.
