Nature's Generator Tracking Order Status

Purchased nature's generator powerhouse platinum pe system on 20 July, 2022. We received the unit and were able to charge the generator once with solar power. Unit would not charge via solar input anymore, soon after we received it, 3 months maximum. We contacted the seller who then contacted nature's generator. Nature's Generator requested many pictures and videos of the unit, the solar panels, the connections, and the control interface/screen. Nature's Generator finally agreed to troubleshoot the unit so we sent it back to them. Weeks later nature's generator tells us that the technicians didn't find anything wrong and that they got the unit to charge just fine via solar. We got the unit back and it still didn't charge via solar input. Every call I make directly to nature's generator using the number listed on the nature's generator website, gets directed to a general voice-mail inbox and rarely do I get a call in return after leaving my name, contact info, and issues with the unit. Now they want me to go through the entire process of pictures and videos just to be able to send it back to them. We just want a refund of the entire unit including the solar panels and cables.
