I recently purchased a 16KW aluminum generator from Ziller Electric. I came home from work to meet the shipper and inspected the package... cardboard, pallet, etc all looked fine. We carefully placed the pallet in my garage and I returned to work. About a week later I decided to do an inventory in order to make plans for installation. After lifting the cardboard cover and inspecting the internals, I walk to the rear and find that the rear panel is pushed in exactly where the flex conduit is stored during shipment. Something obviously pushed on the rear of the unit and dented the panel and two of the air louvers.
I called Ziller twice and left voicemail both times. After not receiving a return call, I called a third time and, upon speaking with their manager, was immediately told that "I had signed for it". I asked for a replacement or someone to come replace the panel and was basically told to take it up with the shipper. I started to get upset at this point and the manager actually started laughing at me on the phone. Nice customer service.
I honestly wouldn't expect anyone to completely unpack a 500 lb generator while the shipper is sitting in the driveway but that's Ziller's stance. I'm in the process of taking this up with both my credit card company and Generac so we'll see what happens.
