I had expensive solar panels transported with them, i did transport the same items as well before without any issues. This time the broke the 2 panels completely by wrong lifting methods which is clearly visible on the fotos available.....they have a part written in their terms and conditions about solar panels, which I understand completely......but that does not give them the right to handle my property the way they like....
