I opted for the Lease To Own feature on dan.com and have been waiting for over a week to receive the domain but the seller hasn't submitted the auth code to transfer ownership. What courses of action do I have now? Can dan.com offer assistance in such situations?

Could the seller be held accountable under the legal terms of the transaction?

My personal experience with Dan's support team has been dreadful as well.
Their European team handles US inquiries, which means that people in the US have to wake up early to reach them on the phone. Additionally, they are unavailable on Fridays.

Even if you manage to wake up early to contact them, they will not transfer you to their payment verification or transfer team. Furthermore, it is impossible to get in touch with team members who can genuinely help with transferring your domain via live chat or email.

Overall, the combined issues of high fees and incompetent support make for an extremely frustrating experience when dealing with Dan's support team.
