I'm sorry to hear that nobody responded to you.
Unfortunately, I'm in the U.S. and I don't have reach to other regions, nor does Samsung U.S. have any connection with this contest. I've sent this up the chain so that someone would respond, but I'll be unable to follow up.
What I might suggest is getting on Facebook and bringing it to their attention as well, in hopes that of the two methods, you'll get a response. You can do that at the Samsung Africa page, and you can find that here.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
