Yep, that's fairly typical. None of the "extras" like this, extended warranties, etc. transfer to new owners or move with you to a new rig.
That's how they stay in business because they know the owner that bought it loses it when they move to something else. Don't buy them unless you plan to keep the rig a while or you get it in writing that it will transfer.
Many have learned like you have... the painful way!
