This is what Hilton answered after I inqured about the status of the points 2 weeks after the transfer from e-rewards.Thank you for your inquiry regarding e-reward. We appreciate you taking the time to contact us.
I would like to request you to please contact e-reward customer support, as checked the account points are not yet exchanged. As always, thanks for traveling with us and please let us know if you have any other questions. You can reach us any time at [email protected].

So it seems the points just disappeared in cyberspace. Off to complain to e-rewards
