We cannot guarantee that sellers will not ship the item before they get your message. As a marketplace, our policy is to not cancel the order unless the seller has confirmed they have not shipped it.
We are sorry for any inconvenience, however, some sellers ship extremely fast and cannot pull items back after they have been packaged and labeled.
