From where should I start ?
Why does the order status show Partially Completed ?
If your order shows that it is partially completed it means that the server cannot deliver any further likes/followers/fans to your post/profile/page [ Mostly because the maximum amount has been already delivered] and the money for the remaining followers/fans/likes will be refunded and added to your balance automatically.
For example : If you ordered 1000 Followers for $2 and the order is half way to completion. Then 50% of the money that you paid will be refunded and added to your balance.
