Faulty product placed back on rack to be sold

I bought Volkano Bluetooth earphones and I was unhappy with the product so I took it back and asked to exchange it. They didn't have a problem and I took a more expensive set of earphone and paid in the difference. I noticed when I opened the box that the earphones wasn't folded like it would be in a new unopened box, but instead of trusting my gut, I plugged it in to charge because it wasn't going on. It charged for forever, more than 2 hours and the charge light never went off. I took it off the charger and it wouldn't switch on. This product was obviously returned because it didn't work and instead of returning it to the manufacturer, the box was nicely tape up and put back on the rack. Why? To inconvenience people to come back? Now I have to find some time in my schedule to go back and exchange it. At this point I don't want to go back to Musica N1 because who knows what dysfunctional item I am going to get next? This is BS.
