Sorry for your run into trouble with this machine and dealer.
Only suggestion I have is to document, document, document...every call and visit. It may be months before it's resolved and you won't remember what they promised 2 months earlier. Who did you talk to (even Phaff Customer Service), what did they say, what's a case number, what happened, when were things ordered, when did they arrive.
We had a situation with a JERK that lasted 4 months and I had EVERY LIE he told us written down (by date and time) from day one. When I filed a complaint with the BBB, it was very easy to retype ALL THE LIES to their online form.
