No Shipping Return label

Im am returning a monitor and have received the email "When you receive your replacement system, use the box and emailed shipping label to return the original system.". I have checked everywhere and have not received this label. Can't get ahold of Customer Support, Live Agent or a Call because its the Long Weekend and the monitor is scheduled to be picked up tomorrow. <To protect you, your private information was removed from public view.
