Game titles missing on my account

I have a question about my games that I had purchased before the origins or the EA app. Most of my games are listed but 2...  SimCity 4 rush hour and SimCity 3000 Unlimited. When I do a search for SimCity 3000 Unlimited it is not even in the EA app for the list of games... Is there a reason for this game not showing up... SimCity 4 rush hour is the game that I purchased. The game was a double pack SimCity 4 and the expansion rush hour but only had2 registration number. All my games were put into my origins app and it showed SimCity 4 and SimCity 4 Rush Hour in my list of games... This is not the only thing that I had had a problem with most of my concerns and game lists were fixed but I noticed my rush hour does not show up, it just says SimCity 4 now... I would like to have my problems straightened out since I have spent way over 500.00 on all my games...
