Dell blank screen replacement in 1 day in South Africa.

The company I work for got me a 28" screen. After a few months the screen stopped working and I went onto Dell's website to check the warranty and saw it was still covered. I phoned Dell support and they done troubleshooting and took my details yesterday and said they will send a replacement. Today I just received the new screen. I have never seen any support move this fast in my history of working in IT.
