I returned 3 pieces of AT&T equipment to my local UPS Store (as instructed) on 7/30/22, prior to the cessation of my service. I have a receipt that shows the serial numbers of the 3 pieces of equipment that were returned.
However, AT&T is only recognizing that 2 of the pieces of equipment were returned.
I called the customer service line and was told that an investigation would be started, and that I could go to att.com/escalations to post a picture of my receipt image. However, the latter web address doesn't exist.
I cannot find an email or other means to show my receipt confirming that I returned all equipment on time.
Can you please tell me where or how I can post or send this information so that I am credited with all equipment returned?
