The purchase on Steam has not arrived on the account

Hello, when purchasing an item on Steam there is a warning: “This DLC will only be available to the Steam account you used to make the purchase. If you have any difficulties, please contact our support service (log in to the site and click the “Send a request” button at the top).” When trying to contact support - there is no site. I only have one account linked to my account, but nothing has arrived to it. I bought War Thunder - T-80U-E1 Pack, Steam login: tjvrm12666. You need to add the product to Райан Г0слинг .

The main account is the one I am writing the request from.

Please log in here and send ticket to our support:
