just recieved this email,
upgrade email in error.
Hello Jkhein,
Monday, June 17th, we mistakenly sent you an email with an offer to upgrade to the Platinum Delta SkyMiles® Credit Card. We appreciate your loyalty and business as a Gold Delta SkyMiles Credit Cardmember, however only Cardmembers who have had their Card for more than one year are eligible to upgrade. Since you are still in your first year of Cardmembership, you are not eligible to upgrade at this time.
We apologize for any inconvenience this may have caused, and hope that you will continue enjoying the benefits of being a Gold Delta SkyMiles Credit Cardmember.
