Hello and welcome to the forums. Looks like you may have came across the wrong spot for help. You can find the Rainbow Six forums here https://forums.ubi.com/forumdisplay.php/64-Rainbow-Six
I would also consider reaching out to support directly through the website as well. In cases where you made a purchase but it hasn't been added to the account, you'll probably need some order confirmation and account info for help. You can create an official support case over at http://support.ubi.com.
