Ignore them at first. If they send a carrier to get the box, tell the carrier it's a mistake and it's already being taken care of at the manufacturer level. The carrier has no idea of the issue. Stick to your story and if they insist past the 4 week mark, go ahead and call to complain or use their chat service if you feel more comfortable that way. Your monitor started smelling like burnt plastic and there was a little smoke coming through a vent, so you got scared and threw it out. Don't say it caught on fire and burnt your dying grandma's house to the ground. Subtlety wins. If they ask why it took you 4 weeks to respond, you were on vacation and couldn't take care of this mess before. Your brother answered the door and spoke to the carrier. Use those 4 weeks to find/photoshop a picture of your burnt BenQ screen in case they require photographic evidence.
