Yeah, noticed that user likes to do so to people calling them out on their behaviour. An entitled person with little in the way of manners. -_-
And clearly not one used to dealing with Steam support.
Sorry to hear Valve won't play nice and supply keys to you, hopefully they aren't a problem to you in the future. It is a pity, but won't blame you for this, I've heard of such issues before, been waiting over a year on some Humble keys. -_-
And a damn shame that a certain user still refuses to read.
