What robots? Apple understandably tries to guide you to self-help methods but it is always possible to get beyond those.
Apple does not do email unless they initiate it. You can contact them via chat, or by phone. Refer to this page for Apple Support features ➔ Contact - Official Apple Support
Select from the presented options until you find a solution for your issue, or see if there is a chat or phone call contact method offered lower on the page (you sometimes have to narrow down the options multiple times before this is shown). If you do not see your issue, keep experimenting with any series of selections until you reach one that offers a chat session or a telephone call and get the representative to redirect you.

What is available if someone is trying to access their account on a different device?
That's a somewhat unclear statement which may be why you are encountering difficulties with Apple's automated systems (and with us too, for that matter). You sign in on the device. If that doesn't answer it then you need to be a lot clearer about what it is you are trying to do and where you are encountering issues.
