Elektronik Billiger — 2 weeks use out of a year long fee

I purchased a windows 2010 update for $109 I received the key code after a couple of attempts I managed to get the full and upgraded use of my windows. However today just over two weeks of use I can no longer get into any of my documents as it is telling me my keycode is invalid. I’m shattered as i need to be able to get into my documents for a project I have coming up in a week’s time. How can people like this continue to scam innocent people with blatant lies and broken promises? I wish someone could track down all these false and rip off organisations and shut them down to protect the innocent ones.
