This thread might give you some more insight:
The issue at hand is that the Samwise Starter Pack was designed to upgrade a F2P account to Premium. Since you are already VIP, that upgrade from F2P supersedes the Samwise one. That is a bug apparently, and the best way to get that sorted out is to contact customer support and explain the issue. It would seem from the thread above that the quickest way to get it resolved is to call them.
