Goods faulty and not being replaced or credited

We purchased 4 X DELL Inspiron 7347's from Drive Control Corporation on 13 January 2015. After returning the laptop to DCC on 26th due to it being faulty we were told to speak directly with DELL. We have had terrible service from DELL and they refuse to replace the laptop even after their technician indicated he did not understand why the laptop was not working and suggested they credit us. <br> <br> I have reported this bad Service to DCC and have had very little joy. <br> <br> Would these companies be happy if they were loosing revenue due to faulty products being sold to them or bad service delivery? <br> <br> The laptop was sold to me on the 13th Jan and we have spent over a week trying to resolve this problem.<br> <br> I'm looking for answers and to get the problem resolved.
