I ordered (among other things) two (cheap) joysticks, the handle was missing from one of them.
Contacted them, got asked exactly what parts were missing, answered the questions. This was in end of May. We contacted them again a few weeks later (I have travelled a lot during the spring), and was asked again what was missing. Answered once more (end of June), then no reaction at all from arcadeshop.de. So, 7 weeks since I complained about the missing part, and it has not been fixed. If it is out of supply, I'd expect to get information, but this has been like talking to a black hole. I'm unhappy.
