Horrid Customer Service From AT&T (...and a secret back door)

We've all had bad experiences with the nightmare of so-called "Customer Service." Not that I want to play Can You Top This, but I'd be surprised - and have tremendous sympathy with you - if you actually can top my recent interaction with AT&T. The issue I had was double-billing of $829.99 for a new iPhone 16.   Here's an overview of what happened:   AT&T double-billed me for an iPhone 16 I invested a total of 10 hours, 53 minutes with a 1 Chat Bot & 21 Human Chat Agents  The Chat transcript is 34 pages long I abandoned an effort to call AT&T Customer Support after being cut off following 32 minutes on hold (Why would I expect the phone company to have a well-functioning phone system???) I miraculously found a place online to file a formal, legal complaint with AT&T's Office Of The President (Trust me, you want the additional info I'll provide below...)
