I filed the chargeback at 1:00pm, and had confirmation from Casper at 9:45am the next morning. After two weeks of being dicked around.

They didn't even ask me when I was available either, just scheduled a pickup for "between 8am and 12pm" two days later. I was very, very tempted to tell them I wouldn't be home during those times ... but at that point I just wanted the thing out of my house.
