This morning I found this in my inbox from Mypoints:
The funny thing is that I entered my number at the time of redemption, and that number is under the "additional contact information" in their original auto reply that has been going back and forth between us. They obviously have not trained their people where to find this information, so this will be an issue on alot of our redemptions.

Dear Judy,
Thank you for contacting MyPoints Member Services.
We apologize for the delay with your Hilton HHonors Points transfer. According
to your Account Statement, you placed your redemption on 1/25/06. Unfortunately
we were unable to process the redemption because MyPoints did not receive your Hilton
HHonors account number when you originally redeemed your Points. Please reply to
this email with your Hilton HHonors account number, along with First and Last Name
that is listed on the Hilton HHonors account, and we will process your request.
Once we receive your account number, you should see the points post to your Hilton
HHonors account within 2-3 weeks.

Please let us know if you have not seen the change in your HHonors balance within
the specified timeframe and we will investigate further.

Please contact us at [email protected] if you have any additional questions.
Thank you for your support of the MyPoints program.
Have a nice day.
Best regards,
Kate H.
