Rather than write my experience with Guy4Game, I've uploaded chat discussions I had with members of their staff. I purchased Tera gold from Guy4Game on 9-10-16. The first chat took place on 9-13-16, the second on 9-17-16, and the last on 9-19-16. After I spoke with Panda on 9-19-16 at 9:20 AM CST, I received the email notice below from En Masse Entertainment (Tera) at 11:02 AM CST of the same day.
