They were rude when I tried to return an item. NVN would not accept my return because the package was open. The product was not used. I purchased two fish finders and network cables. After further review I was not able to network the fish finders. You would think the store would mention that with the items purchased. The return policy for the items I ordered are as followed..."For packages that are returned in an unsealed condition or without the original packaging, a processing fee of up to 20% will be applied to the return."
