"Hey Steam my game didn't purchase right if I do it again will I get double charged?"
"Okay so if you tried downloading it on the Steam client thing try deleting some of these files and purchasing it, if tha doesn't work then do it on your internet browser"
*Checks bank statement and was not charged, purchases again and it works* "Yeah thanks that was so helpful"
Anyway, finally downloading my CoD games, quite quickly thanks to my new internet that doesn't suck
