That's what I think at least. Rather than immediately escalating your concern directly to government authorities, you better exhaust first all available means of directly communicating with the exchange. At least when they finally take notice of your concern, they can act on it right away. Whereas, when CFTC or FTC finally takes notice of your communication, they would still contact the concerned exchange. It will be another round of waiting. Surely, they will also give them ample time to respond. Direct line is always better than going through another party.
Also, there are more avenues than one to reach out to an exchange's support. Besides creating a ticket, there's also email, live chat, social media, and even phone. You can make follow-ups as well.
