Renting a flat
The figures on the viewing are not the figures in the listing.
You have ten minutes in the flat and a number you were told last week.
The situation
The agent names the base rent, the service charge and the deposit, one after another, in a language you half-follow. The listing you saved said something else — and you will only compare them in the evening, at home, too late to ask.
How the session is set up
The listing and the offer you were sent, attached to the session.
Session instruction
Translate what the agent says, then compare every figure with the attached listing. Say plainly which numbers differ and by how much.
During the call
The mismatch, while you are still standing in the flat and can ask about it.
Every part of this is described in Start a session and The conversation window.
