Hello ,[irl name]
Thank you for contacting Steam Support.
Your Steam account 'are4444' has been permanently locked for making unauthorized purchases.
Restricted accounts are blocked from purchasing, gifting, trading, CD Key activation, and the Steam Community.
Since this lock was requested by the cardholder they will need to contact us directly. You will not be able to make any future purchases unless the cardholder requests the restriction to be lifted.
