I think the problem with some people involved with pinball machines is they don't realize 95% of the people doing pinball products, repairs, etc have real jobs also and they likely also have a life outside pinball. So I think the thing to realize is not everyone is pinball 24-7.

I try to reply to every email I get but I can tell you that sometimes it can take a week or more for me to find time to keep up with everyone. And I am semi retired selling a few used parts on eBay and some machines. I wouldn't want to be one of the "smaller" parts suppliers in this hobby. There just isn't enough money in to to make a living at it yet there is too much demand to keep up with at times if you are also working a job.

It is easy to say how others should run their business and I am not saying you are wrong. I am just saying there is more to life than pinball so a reply with in a week or so should be fine in my eyes. Hell they have had major car recalls that take the company months to contact everyone and some of that stuff can be deadly. So you have a broken pinball machine - the world does not stop turning because of that! If an email or two doesn't get you results try calling one evening!
