The tone of some of these replies suggests that if you open up a new,old stock box and find an old cheese sandwich instead of a computer, you still have no right to complain.
If the units are used and refurbished then it should have said so in the sales description.
You wont find that bit of information in the sales description because the criminal mastermind Petro has been coning us all along, what he's actually been doing is driving around Europe in his big van collecting as many used and dirty Escom packs as possible, in order to bring back to his secret layer in Germany for a quick clean up and then flogging them on!
The discoloration to some of these Escom packs has got nothing to do with them sitting in a warehouse enduring changes in climate over a 15 year period, absolutely nothing at all!
