My pre order bonus code wont work

[Athena_Windfeather]

Hi!
After days of trying and waiting for help from the support center I thought I'd come to ask the forums.
My ffxiv account is ran through steam. I purchased the shadowbringers Xpack pre-order through steam too.
I've tried every single possible way of using the Pre-order bonus code and every single time it says it's invalid.
I've used the novice chat in-game, I've sent multiple emails and nobody seems to have a damn clue how to fix it.

Please help me.

As of 15/05/2019 7pm GMT, this issue has been fixed, thank you very much to everyone who helped, ill leave the post here to incase others need to find the help i received, thanks again to everyone it means alot
