I believe we only have 4 years. But they won’t be over for another 3 years. That’s why you really have to keep on top of it, because nothing is really happening at the moment. Only a painter was here and fixed some things. The man was really good. We saw his list and there were quite a few items on the order list / defect list that concern us, but for everything else it said "Kundendienst". The man was here a few weeks ago. My husband sent another email to the site manager today asking how the "Kundendienst" works now. Above all, we should have the "new defects" added to the list quickly, otherwise it will take a long time again.
