Has anyone had any experience with them before?

I sold them an explorer I and got the email about 2 weeks ago saying everything was fine and that I should receive the money in about 7 days. However, since then it's just been radio silence. They're not really responding to emails and every time I call them, they just say they're having a difficult time connecting to their main office and that they'll call me back, which they haven't done

I'm a bit lost at what I can do as they have my watch and I have no idea when I'll get my money. Any advice?
