U2Bviews over delivery

Gave it 250 credits, got 5000 views (and verifying more)
Anyone know if it's a normal stuff?
I see in my analytics a lot of views with 0:00 retention
What do I do?
I mean, it's great to have so much views but what will happen with this weird "zero retention" views?

I have 30k credits on U2Bviews and cant get even one view from them. I put in for 1k views last week and still have not got any of them.... so consider your self lucky.

If you use the "boost" function at least twice you should receive a lot of views. Usually I get at least 7000+ views overdelivered - but like lk_galspanner said, most of them have unfortunately got zero retention.
