Broken Printer, supplier refuses to repair or refund!!!

So i went to these guys, bought a Epson printer, when i took it to my office, it did not work, i took the printer back, they tried to fix it, still no difference and tried to call Epson service for a solution and they were told that they cannot fix it either. Stadex in turn told me they cannot replace it with another one or refund me my money for a machine they very well knew was damaged and broken and blatantly sold it to me!!! Imagine, a businessman being sold s****, how does my office function now as we do printing on a daily basis??? That printer was R4250 which was money out of the business to buy and yet you tell me you cannot refund me??? If that was the case i would have just went to Makro and bought it there knowing that i could return it with no hassles. What kind of business do you people run where you cannot replace a machine yet alone give a refund for your negligence???? Utter rubbish i must say!!!
