So Apple should really be taking action on both counts, in my opinion.
OK.
> when it isn’t
Isn’t that what Apple must check and may be doing by “All they seem to have done so far is forward my complaint to the author of the scam listing” (depending on how they worded that)?
Also, all you formally complained about is a trademark infringement. Global trademark law is complex. Maybe somebody else managed to get a trademark with the same name, too? I guess that’s unlikely, but Apple can’t assume that.

If he did have a trademark he could go to Apple and say specifically "this is a case of trademark infringement" and probably not need a lawyer but he'd also have the basis for a civil lawsuit.
Which is precisely why I asked if there's a better way to report scam apps that I might have missed. But unfortunately it doesn't seem to be the case and you don't seem to have an answer either.
What leads you to make these allegations?
As far as I can tell, it is not pretending to be your app or claiming any affiliation. The app doesn't even do the same things your does. It's just named the same. It seems a pretty obvious app name.
They probably just came up with the name and didn't bother to Google for prior art. Do you have a trademark on the name? If so, that should squash it from the App Store. Otherwise, I think you're hosed.
That said, it's at best a pretty low quality app with atrocious in-app prices.
