I just received a phone call from the Texas Attorney General's office. I filed a compliant with them back around the same time I disputed the charges from TreeGloo to Discover.
They are investigating the issue, and had follow up questions. TreeGloo is apparently claiming they refunded the money of people who placed orders and didn't receive them. I was asked if this was true. I told them the truth, which is that TreeGloo never communicated with me after one stalling email about production issues and that the only way I got my money back was via the credit card dispute.
So filing these complaints works. If you've been wronged by TreeGloo, consider filing a compliant of your own.
