It's just plausible enough to be real, and just real enough to be crushingly depressing. UPDATE: It's fake! But the actual transcript is sort of funny too:
As supplied to us by AT&T, the much more flattering "inspiration" for the prank:
Darlene: I apologize for the problem. Please contact an AT&T Wireless representative at 1.800.331.0500. Unfortunately I do no have access to that service.
robert XX: i'll just jump off a bridge.
Darlene: I'll be right with you.
robert XX: lol
Darlene: I apologize. They will be happy to assist you at that number.
Darlene: It has been my goal to provide you with OUTSTANDING service and that you are VERY SATISFIED with the way I've handled your request. In addition to the survey link at the end of this chat, you may receive a call asking about the level of service I have provided. I hope that you are VERY SATISFIED with my service today. Thank you for choosing AT&T!
Darlene: Thank you for contacting AT&T. Please use the CLOSE button when you are ready to exit our chat session.
Darlene: I haven't heard from you in awhile. Do you wish to continue this chat?
Darlene: I am ending this chat session since I have not heard from you. If you wish to chat with AT&T again, please open a new chat session. We look forward to serving your needs now and in the future.
