I'm actually REALLY glad you posted this question, as I am in the EXACT same position as you. Good to know other chase debit people who ordered through premier are in the same boat.
Also, are you able to pull up your order on https://www.wireless.att.com/order_status/ or just https://www.wireless.att.com/business/order_status/
I can only pull mine up on the business site for now.
Yeah it's definitely nice to know your not alone in this fiasco haha.
And I can only pull mine up on the business site (https://www.wireless.att.com/business/order_status/) as well, not on https://www.wireless.att.com/order_status
