So many complains for pending payments it seems this has been turned into scam and more like OP also lost his interest to run a virtual pig farm, this business model is very similar to a ponzi scam, so better avoid to make investment into this project.
I like to believe in people, at least for a while. Maybe something has happened, maybe he can't use a computer, whatever reason.
By all means don't invest at the moment, but also wait on assuming its a scam.
