Adding to the list of FIXED posts! I'm an EU player so they're definitely going through everyone who calls/chats. Mine got fixed 8 hours after calling up (which had no wait time, I called right as the lines opened for the day, so even tho I half way around the world from the UK it didn't cost much). Account 1 now shows 31 days remaining with BOTH pre-order and CE rewards included. Account 2 is still there, but they said they will be deleting them:
