Hi everyone!

I'm a beginner for this game. There is a problem disturb me.
Before 30 days, I got a friend he is playing FFXIV and he gave me a recruitment code.
I redeemed the code and the website message shown as below:
You have successfully entered your recruitment code
Recruitment Rewards
Friendships Circlet, etc.

But 30 days have passed and I still have not received the item Friendships Circlet.
May I know what happened?
