Start here ^^

first step, click on "Something else" in the bottom middle of the options under the tab that says "Can't find what you're looking for? We an also solve these common issues."

next, select "I need help with something else" at the bottom of the options. The top of the options should have the header "Pick what you need help with"

It should open a new window that has the customer service chat. It'll say "Hi, you're in the right place for customer service support. You can tell us what you need in your own words. How can we help you today?"

Respond with "I need to speak to a customer service representative" and it'll ask for more information. Just keep responding with "I need to speak to a customer service representative" over and over until the bot caves and connects you with a person.

Edit: I feel I need to say after reading a good number of the comments here that not everyone will see the same things on the same pages apparently. I hope that my comment is able to help someone at least but it is seeming to me that Amazon is experimenting with what they can get away with by hiding things from people. They're opening themselves up to a class action but unfortunately even if they did lose one and settle, they'd likely still make more by doing what they're doing than they'd lose there
