HP Warranty (Hemmersbach.com)

I have been promised ANOTHER motherboard replacement for the last few weeks. Initially they supp**** me with a replacement motherboard that had failed unit. However the replacement unit they supp**** me with has a manufacturing defect on it and it never worked since day one. Now they are saying the machine has corrosion and won't replace the motherboard.

So i say if that is the case why did the technician replace my motherboard with this defected board and mot bother to get the system up and running amd just leave site...
