I don't think you used GIN correctly. If you pressed the GIN button it should of closed the auction and informed me that you used the GIN option. It looks like you might of just bid 8888 credit :(
But I did it correctly, I went online and clicked it and submitted the credits. Then it said the auction had ended, but when I got back on my phone it said I was highest bidder and it still had 6 days : /
