BA Exec Club response:

Dear Mr. Burkey,

Thank you for your email. I apologize for the delay in our response.

I am happy to inform you that our records indicate that AT&T miles posted to your account on February 19, 2000. Unfortunately, for security reasons, I am unable to provide details of your miles via email. However, you may contact Member Services at 1-800-955-2748 or refer to your next statement to verify the mileage.
