Conversaciones de pedidos
Every order gets its own conversation, opened automatically when the order is placed. It is the fastest way to reach the other party, and it is the record support reads when resolving a dispute.
Because of that, keep delivery details, screenshots and any agreement inside the order chat rather than in another app.
Notificaciones
New messages appear as a pop-up alert, in the bell menu and on the notifications page. You can turn chat notifications off — along with any other category — under Notification Preferences in settings.
Conversaciones de soporte
Support chat is separate from order chat. Start one from the Support page; it is triaged automatically and handed to a human agent when needed.
Bloquear a alguien
Once you have completed an order together, the conversation menu offers Block user. Blocking hides that person's messages from you and stops them generating notifications.
Blocked conversations are blurred, with a Show hidden messages button if you need to read them — useful when support asks about the exchange. You can unblock at any time from the Blocked Users section in settings.
Conducta esperada
Be direct and civil, even when an order has gone wrong. Harassment, threats and abuse are grounds for suspension. If someone behaves that way, block them and report it rather than replying in kind.
