Issue with the free deck for returning players

Hi
I was coming back in Hearsthone and was greeted with a nice selection of deck ( Rogue, Priest, Hunter, Warrior, Druid ). I was able to play them and the game started a countdown for me at the end of wich I would choose a deck to keep and add to my collection.

The problem being that I never had the occasion to pick this deck. I guess it’s because an uptade came around and messed things up, but I have no free deck and am now sad.

From the 26.0 patch notes:
