Hello,
sorry, so it was my fault, you are right. It is in my e-mail as Steam gift and now it was added to my Steam inventory.
On the other hand it is weird, that there was no notification on my Steam account.
Firstly I was waiting for the key on Steamgifts website, so it was reason why I marked it as "Not Received", because there wasn´t information about Steam gift in your description.
Now I maked it as "Received" nad thank you so much.
Have I nice day!
