Support chat is available on every page of Propfy, signed in or not.
The chat answers from these help articles. When it does not know, it says so and offers to open a ticket rather than guessing. A wrong answer about your billing or your broker is worse than no answer.
If you are signed in, a ticket you open in the chat lands in your ticket list under the "?" menu, and you can follow it there.
If you are not signed in, the chat will ask for your name and email before it opens a ticket, so there is somewhere to send the answer. That is the only reason it asks.
What happens next. A person reads it. Propfy does not send automated replies to visitors, so you will not get a robot email pretending to be progress. Tickets are answered from the same place they land.
The chat cannot change your account, move your money, place a trade, or see your password. Anything that needs an account change becomes a ticket.
