Complaint Review: Camp Out inc

I simply bought a product from Camp Out ( a trailer light modulator $49.95 ) located in NJ. The trailer was a state away Where I did the installation -I noticed after opening the package that a fuse holder, listed in the instructions as included was not. A trip to a local auto parts store , 30min of my time to get the part -  After installing, and spending an hour trying to figure why the product wasn't working properly , I purchased the same product at another retailer that was closer to my location.
It worked flawlessly; proving that the Camp Out bought unit was faulty. (note : I have over 20 years experience in contracting , electrical and mechanical  experience) .
I brought the product back to Camp Out 2 weeks later when I returned to NJ expecting to get refunded for the product , which I had the receipt for. The Manager , who sold me the product pointed to the sign , that said No Refunds - "Ok , well even on a product that is faulty?" He shakes his head and says " well I need to test it" So he does, and he comes back and offers me an exhange for another or store credit. I explain to him , well I already have a working one, and that I'm not in need of anything else. "That's all we can do he says." I ask ask to speak with the owner. He says hes not here, he's in Las Vegas. "Ok well , when will he be back?". "He lives there , we have a store there" he says. "Well can you call him at the store". He calls the owner, and basically the outcome is - "you have to deal with the product manufacturer." basically I get an fu. and an "I tried to be nice " from the manager. Hopefully I don't have to write a review for the manufacturer as well. Stay out of camp Out.
