Yeah thanks, but now, I don't know if is a problem of delay from steam or bot, but, I accepted the trade, and in the history of the steam, I can see that I accepted, but I never received the keys in my inventory...

So I don't know if a trouble with your bot, or only of steam, I won't contact with steam support yet until received an answer from you :) I'll be attentive to news, bless :D

PD: I trust in your page and your work, and understand the delay in the support :) so dont worry for that.

******EDIT: Was delay of steam, if it is useful for someone, I had to open the application, run the game and accepted the keys ingame and then the keys appeared in my inventory...
