Well, I'd be braced to sweet-talk the installer rather than battle with him. Plenty of tea and biscuits on hand. There may well be a good supply of Samsungs out with the installers already, but the sales agent really has guaranteed you something that s/he was not in any position to give you a guarantee about. If the installer doesn't bring a Samsung into your house, it's not the installer's fault. But if he doesn't, and you're nice to him, he might be able to go and get you one ...
