This is what I'd do. You gave them ample opportunity to make it right already.I second @tdhanses, call the credit card company and be done with it. Be ready to send the credit card company all correspondence, including the pictures you sent GoHunt. The credit card company will simply reverse the charges and then let GoHunt eat it or go through the process they should have the first time, and contact you with prepaid shipping ... to get the bag back.
