Hey @junealleyQP!
I can definitely help you out with that request!
The great thing about getting the final billing information, you can do it one of few ways – over the phone, through live chat, or in any AT&T Corporate store location. In order to log into your previous myAT&T account, it does expire the account after 59 days after the phone number is no longer associated with AT&T.
No worries, we got you! Just click on the little link to the right → Contact Us. One of our agents are available to get this matter taken care of for you as soon as possible!
Have a super weekend! Take care! If you have any questions, just reach back out to me through this post!
