I just called 800-395-4922 as mentioned in this thread:

The automated response initially said it was a MileagePlus line so I figured I'd have to explain a lot but it may be a special number as the agent I got had no confusion about what RewardOne was. She jumped right in and I just needed my account #, PIN/password (I changed this to a number before hand because felt weirding sharing a non-numeric password), name, mailing address, and email. Apparently the error I received for the above 3 rewards is expected as she said those must now be manually requested. I requested a 46-point ROEET and she said it can take 3-5 business days to process and I'll received something by email. If anyone of you are waiting until closer to June 30th I say you go for it now.
