Dell XPS not repaired while in warranty

It is supposed to be a superior product, with great after-sales service - as the price clearly indicates...Yet less than 8 months later after \freezing"regularly it simply goes into a reboot loop and crashes. It takes determination to deal with the international call centre who after many calls from our side claim that the software needs to be re-installed and that will be R1499.00 please! What *******! The warranties and whatever else one thought were in place are apparently only for the hardware...What an awful way to treat clients - whatever you do"
