Vivitar www.vivitar.com/support Refused to replace defective 8027 camera. Never used once.Will not read or format sd cards. internet

I have a 160.00 piece of junk Vivitar 8027, that vivitar.com refuses to replace.I reported it broken right after I got it. I have had it for months in the box as the sd card reader inside the camera is broken and will not read, not format,any sd cards placed in it.The sd cards are fine. It is just like the day it came.I reported it over and over and the online "help" just said "it has to be the sd card" I have placed 10 in it as I buy them for other applications same thing does not format, does not work.But they work in everything else.I was told must be your computer. I have two brand new Windows 7 computers now. Same thing, will not read, will not format by camera or by computer via camera. I want my camera replaced or my 160.00 .I prefer a working camera.
