My Computer is fixed but all my personal files and the programs I installed are vanished. I didn't actually expecting that they will format this computer, but luckily I copied my other files including my games, installers and some other important stuff into my USB before they format it and the computer is still slow and laggy. It may took long to install some programs I need so I'll cut off the commissions and return all the points.
I'm not really sure about how to request a refund for a commission until I read FAQ #374: How do I settle a Commission dispute?
I actually tried to use my 2nd account as the fake buyer for my commission. Some days passed until the commission was automatically refunded from my 2nd account.
