I don't know, it sounds to me like the RAM guy has been good about replying and taking full responsibility. Additionally, it's only the 16th (5 days since you last heard from him) and he did say that he was getting ready to move to Texas, so who knows how busy he is. For all we know, he could be in a truck somewhere, driving across the country. I'd wait until next week to see if anything has shown up but I wouldn't cry "foul" yet.
This is unlike my recent dealings with LCK-LED, an order I placed over a month ago and the fact that they're not even replying to any of my emails. That's a situation where I'm pretty sure I'm getting ---fouled up beyond all recognition---. Your situation? Not so much, at least not yet.
With any of these niche arcade-part businesses, it's sometimes touch and go. People are doing other things and their 'companies' are frequently just them and maybe one other person, so waiting more than 5 days, during which the guy is moving, doesn't seem too horrible.
