Cant purchase inquisitor LSB

I tried purchasing the Inq LSB and my card got rejected the first attempt.

 I simply selected the wrong card when trying to purchase, and it didnt go through. I didn't receive the characters, nor was I charged. But I also dont have the pack available in the store anymore to try and purchase it again.

I also tried to use the webstore to purchase and saw the pack there, but immediately got an error when I clicked on it, then it disappeared from the webstore too. 

I guess its a blessing in disguise, preventing me from spending 50 dollars on the game, but I was actually really looking forward to purchasing this one over any other LSB because of the farm and gear investment behind this team, and what they can do for me in the long run. Anyone have an idea of what I could do to get the pack before it expires from the store?
