This isn't exactly fair. You flew off the handle when somebody took longer than they should have and started swearing at them. You should have asked much earlier to speak to someone else or simply started from scratch.
I understand that you're probably worried about your account but this is no way to treat customer service representatives, or anybody for that matter. Next time, take a minute to calm down and think carefully about what you want to get out of the chat, then try with a different person. Even Amazon isn't infallible when it comes to customer service.
I can understand his exasperation. The responses he was getting from the Amazon employee were unacceptable. They didn't even try to understand his problem, or even his name and gender. They're better off with no support than this crap.
My takeaway here is to reflect on how I would have responded to this service incident had it happened to me in person vs. online. I know I would be much less likely to yell and swear in person and I definitely wouldn't wait an hour before asking politely to be assisted by someone else.
Surely Amazon doesn't employ staff that can only use the shift key when caps lock is on? And what is with the habitual ".."? I can't imagine that any review of the chat logs of this person would call them acceptable - it looks like you're talking to the most vacant of teenagers.
Wish the transcript had timestamps. After each message from the rep took anywhere between 5 and 15 minutes. Total conversation was just shy of an hour. I tried to remain calm for a while but this was just nuts.
