It could be seized, but it will be marked as "held by customs".
It could also be lost or your local warehouse is slow.
Do you see at the tracking if they need some additional info for the package or to pay fees? Usually when you tracking it from Royal Mail once it leave UK it automatically gives new link with your local post and local tracking number on the Royal Mail website.
If it was from EU vendor to Greece then it could be only lost or seized. One of my packages (also in EU) was seized and it was +- after 6 days of not moving. And the longest wait was 14 days stuck and then it moved to me.
