What can i do when all of my orders for YT views in June and July were lost?

Hello, i ordered on your website, but i lost all views for many orders in June and July, what can i do to get views back from that seller? i need the seller to refill my orders, if he can not, transfer money back then i order another seller. I'm so disappointed with the service.
