I have been trying for months to contact technical support with no response. I am not able to list anything for sale on their platform. I have sent images and a detailed explanation of the issue and the steps that I took to troubleshoot the issues and I got nothing.
UPDATE: After months, I finally got through to Gunbroker's tech support through their Facebook page admins. After that, it took about a week to find the issue on their end and fixed it. Upgraded to 2 stars
