Bad customer service

I bought a samasung laser het printer. Model C410w Xpress colour laser printer.<br> It wasnt printing correctly there were yellow shadings on the page and eventually it stopped working at all when you power it up.lt used to jam, so i gave it back to incredible connection at the boksburg retail park where i had purchased it from. They sent it to samsung, when they returned it. The printer was starting up however they had depleted the black ink of the toner completely. Now incredible says they cant do anything as that was samsung issue...so now what is the next step further<br>
