Hello,
Have you checked on New Frontier if you still have your crystals on your account, or if they have been used for your subscription ?
You create a character on New Frontier, enter the game, and open the Boutique by clicking on its icon (bottom left on the screen).
You will see how many crystal you got (or not).
If you have no answer after a few working days (4-5), you can send
Wraith02 a PM on the forum with your ticket ID, he will ask what's happening

.
EDIT : i moved your message to "Technical Issue". It will have more visibility, and maybe more answers.
